each row is a repeater, so a repeat of the row above or below, so the code is all the same. I use an on change event on each cell so when you leave the cell if changed it does the update (that all works just fine). the tick boxes on the left do an update on that row as well via an onclick.

So, I entered the data, no problems with “0” in the column.

I then ticked my checkbox on the left and for 90% of them it works, does the update, but as you can see for a few it highlights the column saying “number only” (i have a regexp on the field 0-9 to only accept numbers etc, again that works… but not on a few rows, but, its a repeater so the code is all the same.

there is nothing in the console etc as it doesnt get past browser validation.

i have done several page reloads etc, its always the same rows, of the 26 rows i have in this query 6 have this problem and 20 work just fine

i just cant explain it
