Jotform with long list of conditions not working properly.

My jotform has a long list of conditions sorting out zip codes that are eligible for a donation and some other criteria. The form is very slow and doesn't seem to be working correctly. Only the first 3 questions are supposed to show up until a zip code that is within our donation area is listed. If a zip code outside our donation area is listed then a Thank You page stating we can't donate is supposed to show up. Currently when I try to preview the form all questions show up and the form freezes when I try to enter my information. Could it be that the list of "if then" criteria is too large? Is there another way I can do this so the form responds quicker and properly? 

I've been performing some tests and found an alternative way to get this working and reduce considerably the number of conditions. Here are the steps: 

1. Add a check box field to your form and add as options all the zip codes you want to allow on your form.

2. Remove the current conditions you have and add one that will insert the value from your zip code field to the check box, example:

This guide will help you passing the value from one field to another: https://www.jotform.com/help/286-How-to-Pass-Field-Value-to-Another-Field

Then you may simply set the condition based on the check box, if check box is filled then show the fields, the same for the redirection. 

Kindly give it a try and let us know if you have questions. 

That worked beautifully!! Thanks so much for your help!
