I am having the same issue. I am pretty new to glide. The issue is that when I am clearing the form, it doesn’t seem to send it to Airtable. So whatever value was set in Airtable pops back into the form after maybe 10 seconds.
The row is user protected, the column is not user specific.
I don’t have an answer for the airtable issue, but I think it would be much easier, simpler, and safer to just have a single row for all users instead a row for each individual user, and then use user specific columns to hold the values for your custom form. The user specific columns will keep that temporary data within glide and also eliminate any unnecessary syncs to airtable until you actually submit the form and write the values to the permanent table.
