Conditional logic enabled checkboxes

Hi! First off, I want to say how amazing your product is - I've tried a bunch of different form builders, and Gravity is by far the easiest to use, particularly on complex forms.

Next, my question: I'm building a registration form for a school website and one of the questions is how parents would like to be notified of their child's absences (Home phone, cell phone, or email). Is there a way to only have the checkboxes for which the parent has input data be shown in the question, or does that require having three different questions, each asking about a different contact method?

Thanks!

It's on an intranet right now for testing, so I can't give you a link, but perhaps I can explain it more clearly.

As parents are filling out the form, they must enter a home phone number, and they can choose to enter an email address and/or a cell phone number. The question is then asked which they would like to use to be contacted by the school (Home Phone, Email, Cell Phone), but I don't want them to be able to pick "Email" if they haven't entered an email address earlier in the form.

I can figure how to make a whole question appear or disappear based on previous answers, but I can't figure out if it's possible to make certain options within a question appear based on previous questions.

I hope that's more clear. :)

I'm looking for something similar to this.

I need to be able to disable options in a set of radio toggles based on the answer to a question proposed by another radio toggle earlier in the form.

For example:

Question 1 - This is a:
• Faculty Purchase
• Staff Purchase
• Department Purchase

Question 2 - PC Type:
• Desktop PC
• 13" Notebook PC*
• 14" Notebook PC*
• 15" Notebook PC*

*this option should be disabled if Staff is selected in question 1 as a notebook pc is not available for Staff purchases
