Hey guys,

I'm running an email script which works fine but only want it to run through the last row with data in it. I don't need it or want it to run if there is no data obviously. How do I reflect that in the example script below?

For example, say there are only 3 rows of data in my sheet. I only need the script to run for those 3 rows but the code will run for 20 rows. The number of entries to process will vary by the day so I can't just set it at a set number.

Basically I'm looking to replace
Code: 
[COLOR=#000088][FONT=inherit]var[/FONT][/COLOR][COLOR=#000000][FONT=inherit] numRows [/FONT][/COLOR][COLOR=#666600][FONT=inherit]=[/FONT][/COLOR][COLOR=#000000][FONT=inherit] [/FONT][/COLOR][COLOR=#006666][FONT=inherit]20[/FONT][/COLOR][COLOR=#666600][FONT=inherit];[/FONT][/COLOR][COLOR=#000000][FONT=inherit]   [/FONT][/COLOR][COLOR=#880000][FONT=inherit]// Number of rows to process[/FONT][/COLOR]
with some iteration of .getlastrow...I think?

Code: 
[COLOR=#000088][FONT=inherit]function[/FONT][/COLOR][COLOR=#000000][FONT=inherit] sendEmails[/FONT][/COLOR][COLOR=#666600][FONT=inherit]()[/FONT][/COLOR][COLOR=#000000][FONT=inherit] [/FONT][/COLOR][COLOR=#666600][FONT=inherit]{[/FONT][/COLOR][COLOR=#000000][FONT=inherit]  [/FONT][/COLOR][COLOR=#000088][FONT=inherit]var[/FONT][/COLOR][COLOR=#000000][FONT=inherit] sheet [/FONT][/COLOR][COLOR=#666600][FONT=inherit]=[/FONT][/COLOR][COLOR=#000000][FONT=inherit] [/FONT][/COLOR][COLOR=#660066][FONT=inherit]SpreadsheetApp[/FONT][/COLOR][COLOR=#666600][FONT=inherit].[/FONT][/COLOR][COLOR=#000000][FONT=inherit]getActiveSheet[/FONT][/COLOR][COLOR=#666600][FONT=inherit]();[/FONT][/COLOR][COLOR=#000000][FONT=inherit]

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.
Sort by date Sort by votes
Figured it out! For anyone wondering, this is what it looks like:
