Testing for Null Values

[Bhujanga]

I have a form where the user enters various fields of information. Some of these fields may be left blank until a point in time when the user is ready to issue a permit. At that time they will click a button that unleashes a sequence of events that ultimately results in the aforemntioned permit being issued. The first events is a data checking routine, to make sure that all the values are appropriate for this action. I'm able to test most things quite easily. However when a field is null and I use the following syntax:

If Me![OwnerNo] Is Null Then
MsgBox "You must enter a valid Sign Owner before issueing a permit."
Exit Sub
End If

It reurns the message "Object Required", while the following command works fine:
If Me![NewStatus] = "I" Then
MsgBox "You must change the status to something other than 'Illegal' before issueing a permit."
Exit Sub
End If

What gives?

Also, Is it not possible to assign background colors to tab pages?

Thanks!

The proper syntax in VBA is

If IsNull(Me.OwnerNo) Then

Linq ;0)>

That's what I needed. Thanks

Glad we could help! BTW, the inverse syntax in VBA would be:

If Not IsNull(YourFieldName) Then

Linq ;0)>
