How do I limit the length of a text field?

[ep820]

I want users to fill in text in a text field up to the bottom right edge, then have the box not allow any more characters to be typed. As it is now, the box enlarges as long as they keep typing. I need to do this because the text field appears on another layout that has space limitations. Is there a way to "lock the box" or even specify how many characters it can hold?

EP, in the field definitions window select your text field and click on options, go to the validation tab and select validate by calcualation, there create a calculation that looks like this

Length (txt) < 20

where txt is your field name and 20 is the max amount of characters, below that calcuation box is a message box where you can specify the message to the user.
