Topic: Amount cell bug in customer_payments.php
I've tried to add an amount cell in this file. Usually, the inputted number will be automatically formatted. Instead of automatically formatted, it do nothing and I get this error in firebug :
TypeError: document.getElementById(...) is null
var val = document.getElementById(doc).innerHTML;
utils.js (line 250)
In this file, I already modified it and guess maybe my modification caused it. So I changed back to original version, but nothing had changed.
I use 2.3.20 and only half of it updated to 2.3.21 because I've heavily modified it. Anyone can help?
