I have reworked my form, I have added a checkbox selection with 10 possibilities. After trying to edit a stored record, the following failure appears: Query failed: Unknown column 'element_28_11' in 'field list' ....
There is no field 28_11! If I create with phpmyadmin a field ...28_11, the new message: Query failed: Unknown column 'element_28_12' in 'field list' .... appears....
So, there must be a little bug ... Who can help to fix it?
