Form conditions issue - Hidden fields showing

start time should only show if I want to change the start time is selected, but it is showing on load.

Actually you have no conditions to show 'start time' if 'I need to change... start time' is check.

There are two conditions linked to 'start time', since the field is already hidden, adding hidden conditions for it again is a problem, and even if the field was hidden when the form is loaded, it will only display if all two conditions match. 

Since the field is already hidden initially, remove the HIDE blocks and use the conditions to only show the field when needed. Also avoid mixing SHOW and HIDE conditions as it can result in conflict.

I had deleted those conditions that you can see and they aren't showing up when I check through all the conditions.

I don't know how you can see them and I can't, but I am unable to clone the form you've linked I get an error that it doesn't exist.

Have you resolved this already? I just checked your form and the Start Time field works as expected: https://form.jotform.co/60946887625876

I'm not sure what is going on. It seems to be taking a long time for conditions put in place or removed to have any effect.

On some of my forms yesterday all conditions were removed after I deleted one and I had to revert to a previous version of the form to get them back.

But it does appear to be working as it should now.

That's odd, but good to know it is properly working. Open a new thread if you need anything else, we will be glad to assist you.
