Hi.

I'm trying to get certain fields for numbers only and certain others for letters only. When I open Text Field Properties, there is no option for numbers or letters only. Really stuck! (also, don't have a clue where or how to do coding if needed...!)

Thanks!

This can be done using a custom Keystroke script.

For example, this one will only allow numbers:

event.rc = /^\d*$/.test(AFMergeChange(event));

And this one will only allow letters (both lower and upper case):

event.rc = /^[a-z]*$/i.test(AFMergeChange(event));

This is nearly perfect for me.  I would like to use event.rc = /^[a-z]*$/i.test(AFMergeChange(event)); but also allow for a space.  My intent is to use the code in a "City" field.  Some cities, like San Francisco, require a space between two words/letters.  Is this possible?

Thank you, but I'm not sure how to do this.

How do I apply a custom keystroke script?

Right-click the field in Form Edit mode, select Properties, Format, Custom and then click on Edit next to Custom Keystroke Script and paste the code into the window that opens.

It's possible that after you do that the selection will revert back to None. That's OK. Just click on Close and it should work.

Thank you for your quick reply. Much appreciated.

.... Problem is, when I go into Properties, I only have 4 tabs, (General, Appearance, Position and Options)! (No Format option!)
