Character Verification 追蹤

Brent Wiebke

I have created a data entry form and have been successful in controlling the characters and qty of characters and now I would like to take it one step further.  I would like the application to verify the data that is input.  If the first character isn't a "4" then it would give and error, if the third wasn't a "1" and then it would give an error.  I'm sure with some VB skills this would be no problem, however I lack those skills so it will be starting from the basics to learn.  I'm hoping there is another field I missed that could control this.  Thanks for the help.
