    The Alphanumeric validation on the textbox does not allow hyphens in it, you may only enter letters and numbers. As a work around what you can do is to specify the format of how the value should be added using hover text and show a hint example. To set the limit on the field simply select the textbox from the toolbar click on Max Size. Below is a sample form that includes a textbox following the suggested work around.


    Hope this helps, let us know if you have further questions.
