Hi all! I'm trying to summarize deliverables using the date stamp of when a form was submitted. Unfortunately the way our form is set up, we have employees fill out a form and enter the month and the year separately so our sheet does not have a normal date column. Is this possible to use the Auto/Number system column as a traditional date in a sumifs formula? The equation I'm using doesn't come back with the UNPARSEABLE but it is saying the sum is 0 when I know there are actual numbers that have been reported. Also, this is an equation referencing another smartsheet, which is why it says Range 1 instead of the column name. Thanks for any and all help!
=SUMIFS({Monthly Reporting & Deliverable Tracking Range 1}, {Monthly Reporting & Deliverable Tracking Range 2}, "Riparian Buffer Implementation (ac & ft)", {Monthly Reporting & Deliverable Tracking Range 17}, "07/29/19 12:00 AM - 07/15/20 12:00 AM")
