Deep Dive | Friday Functions Series: Provide Character Limit Awareness (while typing)

Learn how to create a dynamic count of the characters while someone is typing. This can be helpful in forms where the submission should be limited to a certain number of characters and avoids the consumer being presented a server side error. Note: You can also set the max length property of the input control to 122. In that case, they actually can't type more than 122 characters to prevent server-side errors.

P.S. The formulas should go into the text labels where you want the numbers to be shown (in the Text property). Both formulas are leveraging the "Len()" function. Works just like it does in Excel too!
