VBA Code: Problem integrating a Sub into a Module - Vlookup problem? Please Help

[Nick_86]

Hi all, I'll try my best to explain. I've spent hours working on this code and it all works fine when I test each individual Sub. However, when I put each of the 4 Sub's together into one Module (Module 3) in a Master Worksheet and then try and call them from the master Sub, the first 3 work but the last one (Sub FindKWH, which is a vlookup) doesn't work.

What it does

The main excel file with the module in it has 4 sheets (Sheet1, Sheet2, Sheet3, Sheet4). Sheet 4 has a list of file names in Column B (I've limited it to 4 for this example to save space, but in reality there are 240 files/240 rows in Column B listing their names):

Sheet4, COLUMN B (4 rows):

Log_20150714150847_GPRS_SN_020141100181_PMD_SN_0234891104.csv

Log_20150714150907_GPRS_SN_020141100152_PMD_SN_0234891144.csv

Log_20150714150927_GPRS_SN_020141100199_PMD_SN_0234891123.csv

Log_20150714150944_GPRS_SN_020141100191_PMD_SN_0234891132.csv

Sheet3 is blank and this is where I want my data populated with Column A for the file name, Column B for Date and Column C for a number (KWH value).

The macro does the following: it looks at each file name in Sheet4, Column B (one at a time), finds that file (which is a CSV file) in the specified folder, opens it up and then through the use of each of the 4 Subs (AddRows, SumDaily, Dates, FindKWH) it does the following respectively to manipulate and format the data how I want it before copying and pasting to the main file Columns B & C (Column A being the name of the file where the data came from):

1. AddRows: Adds 2 blank rows between each day in the data (the data is half-hourly, so there is a column for dates having 48 dates that are the same with a time column next to it that increments by the half hour, i.e. 0:00:00, 0:30:00, 1:00:00 etc. and then a kWh figure in the next column for the Kwh's used in that half hour period). So there are 48 rows for each day then 2 blank rows, then 48 rows for the next day, then 2 blank rows etc. Hope this makes sense?

i.e. (the space between 25/02/2104 and 26/02/2014 are the two blank rows that are added by AddRows, there are no blank rows between each day when the Worksheet is first opened):

25/02/2015	22:00:00	321
25/02/2015	22:30:00	279
25/02/2015	23:00:00	291
25/02/2015	23:30:00	331
26/02/2015	0:00:00	242
26/02/2015	0:30:00	157

2. SumDaily: It takes each day (so the 48 rows with the same date) and outputs into Column J only one of each date. Next to that date it gives the total value of the kWH summed in the 48 rows for that date (so a figure for the kWh's used in that day).

3. Dates: As the half-hourly data skips some days here and there altogether, this Sub takes the first day found from step 2 (i.e. the date in J1 where the list of dates start) and the last date at the bottom of the J column and then populates the full list of dates in Column N including any days that were skipped.

4. FindKWH: Now I have the full list of dates without any days missing in Column N, this Sub does a Vlookup of each days in Column N, finds that date in Colum J and returns the KWH number next to it (i.e. in normal Excel it would be =VLOOKUP(N1,$J$1:$K$225,2,FALSE)) if there were 225 rows for example. For days that are missing it returns a value of 0.

So Steps 1-4 are run for each Worksheet that is opened by Sub HHD(), and it takes the results (Columns N and O where the complete list of dates and the KWH used on each of the dates are) and pastes them into Columns B and C in the main Worksheet. Next to each of these rows with a date/KWH number, it gives the filename of where they come from. It then closes that Worksheet and opens the next one, with the results (Columns N and O along with the file name) being pasted into the next free row in Columns A, B, C in the main Worksheet.

The end result of all of this should be 240 Worksheets that have been opened, manipulated and then had the results pasted in Columns A, B and C of the main Worksheet.

What actually happens when I run this Module is it works through it all and I end up with a list of file names and dates in Columns A and B, but no KWH figures in Column C.

Any help with what's going wrong (I'm sure the error must be in Sub FindKW) would be much appreciated.

Here is a link to download the Worksheet and example files: http://www.filedropper.com/dataanalysis-july2015
Just need to change the line srchPATH = "C:\Users\Nick\Desktop\Data Analysis - July 2015\HHD\ to the address of where the folder is on your Desktop once you've unzipped it and you can run Module 3 and see what happens.

I've also found another problem with this Module. For some reason it is not taking the entire range of the full list of dates generated in Step 3, it chops some rows off near the bottom. This doesn't happen when I use each module individually on a single Worksheet. Just can't figure out why these errors are happening...
