Wrong Data Type - Too Many Characters - But That's Not True

I have a form [FA1_OrgMaster] that has a Combo Box [cboCounties].

The cbo's Row Source is a Query with 2 columns - [TYaa_CountyNumber] -
Integer, and [TYaa_CountyName] - Text 50 characters. The first column -
CountyNumber - is Bound, but only the 2nd is displayed to the user in the cbo.

I have a Form Open Event Procedure - but it doesn't affect the cbo.

I have a Form Load Procedure that does:
_______________
Private Sub Form_Load()

On Error GoTo HandleError

Me!cboOrgs = Null
Me!cboCounties = Null
Me!cboCounties = "Choose County"
Me!cboCounties.SetFocus

Exit Sub

HandleError:
...
Exit Sub

End Sub
_______________________

I've clicked the cbo, oh maybe 1000 times. Works perfectly about 95% of the
time - but I get an error message without an error number about 5% of the
time - "Wrong Data Type or Too Many Characters ...".

I can't see a pattern leading to the error. I've gotten the error when:
* click the cbo immediately I open the Form from the Database Window
* go from Design back to Form View and immediately click the cbo
* click the cbo after I've been jumping all around the form, entering data,
etc

But most of the time I do those things I don't get the error. I've never
been able to replicate the error by repeating what I think I did.

When I get the error message and click OK, sometimes the Cbo "drops down"
immediately. Other times I have to click the down arrow on the cbo. So - even
with the error message, the program proceeds normally without my having made
any changes other than click "OK" on the error message.

I'm stumped. Any ideas?

Thanks

Click to expand...

The first problem I can see is that you've bound the combo box to a numeric
value (TYaa_CountyNumber) but in the Form_Load event you're setting it to a
string value ("Choose County"). Shouldn't you be setting the combo box to
the numeric value that corresponds to the string? That might be a place to
start looking.
