I just tried it on mine and it behaves as expected, all negative values are hidden. Before you turn on filter, try selecting the entire sheet by clicking the box above the ‘1’ row header, and to the left of the ‘A’ column header, then turn on the filter to be sure it’s filtering everything. I suspect you may not be filtering the entire sheet.
Thank you. It worked but I sure don’t know why it worked this time but not before. I tried it every which way including a separate Google Sheet (which worked) but I couldn’t get it to work in Tiller.
Excuses … excuses. It works now and I’ve saved the filter for future use.
