Help adding app alert for character limit

[#1]

Good Afternoon,

I am working on making permit applications into fillable PDFs. My last hang up is our description dialog box. I have added a character limit to the box but would like  away to inform people they reached the character limit. Is there a way to create an app.alert for this or another type of notification?

Any input or help pointing me in the right direction would be greatly appreciated!

Thank you!

Use this code as the field's custom Keystroke event:

if (event.fieldFull) app.alert("The field is full!");

That worked! Thank you so much for once again being so helpful and making the answer so easy!
