I am using hidden fields to store values for conditions. Basically what I do is run a javascript that uses a regex to find the specific field I want, take the value, evaluate it through a script and set the value of the hidden field either as true or false. This works when the field is basic text, but when I select hidden field it does not. Shouldn't it work both ways?

I checked the page source code on the preview survery and there should be something like:

 <input type="hidden" id="hidden1" value="valueofhiddenfield" />

Instead the whole tag is missing. Can you tell me where to look for it in order to correct this?
