I've brought this up before and I'm going to give this one more shot before I open a support ticket.
The Annual CPI Adjustment cell is populated from the sheet summary using a formula to pull the rate from another sheet where the rate is calculated. On my test sheet, this workflow runs perfectly, but my LIVE sheets, the box will not check unless I use the RUN NOW option on the workflow. I tested this again today on my test sheet (to make sure I'm not crazy) using the sheet summary and manually entering a rate in the cell. I don't understand why it will work on the test sheet, or if I manually run it. It worked once or twice when I first rolled it out, then stopped on every sheet. I'm totally frustrated.
