DLOOKUP For Button

[Bandara]

This is my DLO0KUP Query

Me.BalanceA = DLookup("Balance", "CardDetails", "CardNo='" & Me.Combo60 & "'")

When I add this to Combo Box It work and show the result in the form field. But When I Add this to my Submit button it doesn't Work?

Why is it?

But When I Add this to my Submit button it doesn't Work?

what do you mean add it to the submit button?

that doesn't make sense. you can't assign a formula to a button. are you talking about *throwing it* into the combo box after the button is pressed? on the other hand, your form field depends on a value being in the combo box. if you're pressing the button without a value being in the combo box, of course it's not going to work. then again, you could have the wrong syntax behind the button too.

I haven't used access forever, but I think so. maybe something like this behind the button:

me.newBalance = DLookup("Balance", "CardDetails", "CardNo='" & Me.Combo60 & "'") +
me.recharge
