You must test here LEN(ALLTRIM(this.value)) as David Moore already said.

>=messagebox("Transit Number must be 8 characters [ie. 12347879] !",16,oCUWS.appname)

You don't need to test the length here. It has to be 8 because you're on the ELSE of <> 8.
> if right(this.value,4)<>"7879" and len(this.value) = 8
Why showing a message? If you already know that the last chars must be "7879", you can fix the value if it's wrong. Why force the user to type "7879" each time?
