Can use Conditional Formatting to disable textboxes or comboboxes.

Is it also possible to make the 3 disable input be converted into 0 value? because those 3 disabled fields (amount) are in a calculated format. thanks

Can have conditional expression that displays 0 when box is checked.

=IIf([checkbox], 0, other calc here)

But if these textboxes already have calculations then why need to disable? Cannot input value to a textbox with an expression or if bound to query calculated field.
