Spending Trends-Income/Expense Breakdown not populating

Hi everyone-
I am new to Tiller, using the Excel version. I added a Group column onto the Transactions worksheet (in column C); now, the the bottom part of the Spending Trends worksheet (income/expense breakdown section) is not populating. I see errors in the hidden formulas, but do not know how to correct.

After reading a post on here, I tried to move the Group column to the end of the Transactions worksheet, but it did not correct the issue.

Thanks in advance for any help you all can provide.

I figured it out, I added groups within the table in categories. I moved the group column and found an incorrect array. I almost gave up, but glad I figured it out!
