What field's limit character count not work for you. Could you share the form url?
It works for me for state (althought you might want to set the min to 2, only the max is set right now) and student number (min and max are 9 chars) but it doesn't look like you set up a min or a max char count for the telephone numbers. Please confirm that you set up the min and max for those fields correctly.
For state, I set the min to 2 and the max 2
For student ID, I set the min to 9 and max 9
For zip, I set the min to 5 and the max 5
I'm sorry. It works fine. When I tested it, I kept putting in the correct characters and did not realize it will not let you could not complete the form if you exceeded the count. THANKS
