If Statement to rid of DIV/# - Also have SUM statement included

[RO24]

Morning - I am thoroughly confused on a report that I am doing a lot of data analysis on. Below is an example of what I'm attempting to do, which for all intents and purpose is doing what I what it to do within my main sheet ( I would attach, but my computer system is weird).

Items Units TOTAL TURNS
JAN 22 JAN 0 JAN Morning -
FEB 19 FEB 2 FEB 9.5
MAR 0 MAR 4 MAR 0
APR 14 APR 0 APR
MAY 5 MAY 3 MAY 0.56
JUN 0 JUN 2 JUN 0

This is the formula used to calculate the "0" in Total turns at the bottom - =IF(G7=0,"",C7/($G$2+SUM($G$2:G7)))

In my main spreadsheet I'm really confused on why I'm getting a DIV in some rows and a blank in other rows, with the same formula and what seems to be the same way to calculate. This is all being done within Power Pivot as well, so it's an enormous spreadsheet, which I know has nothing to do with.

Thanks for any help.

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
