macros/formula to calculate between adjacent cells

[olutoyin]

Thank you for your usual assistance on this forum.

I am designing a model that can be used to calculate payment/usage patterns of customer.
Each customer has a unigue ID and has access to credit facility which runs a monthly cycle.

Payment: If the value on the preceding cell is less than the current cell then a payment has been made.
Usage: If the value in the preceding cell is greater than current cell then usage has occurred.

Please values in a cell could be negative or positive.

Negative implies customer is using credit facility while positive means using his own resource(payment made is more than credit owed).

I need a macro/formula that can be used to calculate both payment and usage over a monthly cycle for each unigue customer.

Please find below a sample table for better understanding.

Thank you.

This is probably going the hard way but the you can try.
In another sheet in cell B1 enter
=IF(Sheet1!B2="","",IF(Sheet1!C2>Sheet1!B2,1,0))

where Sheet1 is spreadsheet with your data.
Copy this down and accross.
This will gove you a range of 1 and 0

Then on the first Sheet use SUM(IF) formula to get the values related to customer.
I have attached an example for better understanding
