IsMatch Optional Digits Single Digit Only

[Alerts_OM_USA]

I am trying to use the IsMatch to verify a TextInput of Time. Currently it is

IsMatch( TextInput1_1.Text, OptionalDigits & Digit & ":" & Digit & Digit)

. This is so the user can type in 5:00 and it would work. The problem is that the user can also type in 125:00 or 213455135:00.

Is there a way to just allow a single optional digit?

Could you combine this with the LEFT or RIGHT function and only return a single value to the left of the : sign?

edit: I ment left/right, sorry

Thanks, that worked. I then discovered though I could just set the maxlength of the text input to 5 so the user can't even type in more than that.

That is what I wanted to suggest.
