@solotheking, when I quickly checked your XLSForm the first thing I noticed was the total number of choices. I observed that you had 682 teacher
under the choices tab. When you have such a huge list, I would advise you to user the external choices to cascade as outlined in our previous post:
When you have that long cascading selects, the form time-outs.
The other thing I also noticed is that you have used multiple colors within your XLSForm. Try removing them as it’s taking up a lot of unnecessary space.
