I am stuck here, it keeps saying the formula is invalid. Need some help!!!
Make sure you spelled the line item in SYS00 the same way as you spelled in your formula. The error is saying it doesn't recognize the name Forecast Period?. Perhaps you left the question mark off, or left a space after the Period
Thanks Jared, I saw my error. I did not spell the line item fully. I named it 'SYS00' instead of 'SYS00 Time settings'
