Is there a way to limit the number of Characters someone can type in a text box?
Click on the text box where you want to limit the number of character and go into 'custom validation model'...all the way to the bottom of the window that opened up when you click on the text box
Use a 'get text length' component and then a 'compare numbers rule' component
Theres also a Maximum Length property on the Appearance tab under Format. Probably a little easier to use this.
