Can i limit data that users can edit?

Unfortunately there is no condition logic yet that can make a field Read-Only to be able to locked them from edition. 

There is show/hide or make fields *Required base on condition, but no lock/unlock option.

A workaround conditional statement you can use is the Populate/Update fields base on Condition.

user guide: -How-to-Populate-Field-with-a-Value-from-another-Field

But this will require creating multiple duplicate fields, 1 for the actual answers, and then 1 for the read-only field.

Example form: http://www.jotformpro.com/form/50988616180968

In the test form, when you click on I Agree it will display a different fields that are read only.. so you cannot edit them.

Let us know if this workaround can work for you.

I will also submit a feature request ticket to have the capability to lock/unlock fields base on a condition.

Thanks.
