I have a form with a sub-form within.
The main form consists of 3 fields. The first is a combo box "Materials/Description of Work", the second is "Unit of Measure" and the third is "Quantity".
I would like the combo box to disable itself once I tab to the sub-form - this is to prevent accidentally changing the selection in the combo box.
When I go to a new record I would like the combo box to be re-enabled so I can make a new selection.
I am only now learning how to write code so I need all the help I can get.
Thanks in advance for your input
