In my form there is a field known as CurrencyCombo. I want the user to select currency from this CurrencyCombo before proceed to the rest of the fields. If the user didn't select the CurrencyCombo, then i want it to set focus back to CurrencyCombo until the user select.

Below is the code:

Private Sub CurrencyCombo_Enter()
If Me.CurrencyCombo = Null Then GoTo CurrencyComboErr
If Me.CurrencyCombo <> "" Then GoTo ExitSub

CurrencyComboErr:
MsgBox "Please select currency"
Me.CurrencyCombo.SetFocus
If Me.CurrencyCombo = Null Then GoTo CurrencyComboErr
ExitSub

ExitSub:
End Sub

After i run this code, the user still able to go to other field eventhough the user didn't select currency.

How can i make so that the user have to select the currency and "disable" to get out of this field if the user didn't select the currency?

Place this code in the AfterUpdate event of the combobox;

If Me.CurrencyCombo = Null Then
MsgBox "Please select currency"
Me.CurrencyCombo.SetFocus
Docmd.GoToControl "CurrencyCombo"
Else
Exit Sub
End If

Dear Daniel:

I tried the below code:

Private Sub CurrencyCombo_AfterUpdate()

If Me.CurrencyCombo = "" Then GoTo CurrencyComboErr
If Me.CurrencyCombo <> "" Then GoTo CurrencyComboExit

CurrencyComboErr:
MsgBox "Please select currency"
Me.CurrencyCombo.SetFocus
DoCmd.GoToControl "CurrencyCombo"
GoTo ExitSub

CurrencyComboExit:
Me.InvoiceExchangeRate = Forms!Invoice!CountryCodeSubform!ExRateFXtoMYR
DoCmd.RunCommand acCmdSaveRecord
GoTo ExitSub

ExitSub:
End Sub

BUT it still doesn't work. The user still can leave the currency field blank without selecting it from the combo box.


What wrong with my code?

Hmmm weird,

Maybe workaround, there must be an easier way to do this, set the validation rule in the field properties of the field which is related to the combobox...

Or if its always required, then set the field propperties on Required.

Daniel

ok
thanks

Hi
Would it a better option to place your code in the "BeforeUpdate" event of the form, placing your code in the "afterupdate" event of the combo will not trigger "unless" you select something?.
