What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
There is no specific number of conditions that you can have on your jotform as depending on the jotform their number increases or decreases.
Now, some jotform's conditions can also be further optimized, which might be the case with your jotform, allowing you to have more conditions with more speed.
These cases are often good to avoid:
1. big jotform with a lot of conditions for each specific field
2. big jotform with a short time frame to save data (for continue later option)
3. big jotform, with short time frame to save data and a lot of conditions.
If you can give us a link to your jotform ( I presume that it is this: http://www.jotform.us/form/43303394338151 ) we could take a look and see what might be the issue. The jotform above however opened properly and quickly for, so if there are any specific steps that should be taken, do let us know.
