I have a card that requires the user to enter some text to fill out some variables in a form.

I encountered a problem where the user could hit the return key,
placing a CR after the entered text.

I am guilty of doing this myself, while filling out forms, most of the time it would not matter however in this case, a CR is not wanted.

I began to wonder if there were a way to make sure that there is not a CR in the field, as the rest of the script depends on each line of the script to be on its own line.

So a CR in a text field, would create a new line where it is not wanted, which breaks the script.

Any thoughts on this, I tried a couple of different things, but it appears that even if you use the IF statement the field will still accept a CR.

Thanks in advance for any suggestions.

The easiest method is to set the 'autoTab' property of the field to true. This way the engine will automatically 'tab' to the next field if the user enters a CR into the field.
Note that you can still allow multiple lines in such a field by tweaking the height: if two lines would fit without causing the text to 'scroll up' then the return won't send the focus to the next field until the user hits CR a second time.
Also look at the 'returnInField' and 'enterInField' messages in the Revolution dictionary.

Hope this helped,
