I tried to change the following from:
text_row(_("Item Code:"), 'NewStockID', $tmpCodeID, 26, 25, null, "", $post_label);
to
text_row(_("Item Code:"), 'NewStockID', $tmpCodeID, 41, 40, null, "", $post_label);
It does not work. The field still remains at 25. When I was using a previous version (2.3.xx), I changed from 26,25 to 41,40 and it works. Not sure how to do it in version 2.4.13. Any help is highly appreciated.
