Validation Rule

[Guest]

Is there anywya to have a validation rule that specifies that the value in
the tex box of a type string is either an integer or equal to "Unlimited"

You can write code in your control's BeforeUpdate event procedure to check
this, but it would be hard to do just as a ValidationRule.

I'm sure that you can do it other ways but how would you do the line: ElseIf
[text1] = Integer portion of the following if-statement:

If [text1] = "Unlimited" Then
.....
ElseIf [text1] = Integer Then
Else: Throw Error
End If

Dan, it would make more sense to me to use a Number field, and display the
word "Unlimited" on a report for Null.

I like Allen's suggestion, but if your users require otherwise, you could
use IsNumeric to determine whether the entry is a number, and either InStr
with a "." or Int([text1])=[text1] to determine whether it's an integer. Be
sure you do the IsNumeric test first, though, or Int could throw an error if
it's a string.
