Submit form with variables

Hey,

This is probably a really simple question with a simpler answer. I want to submit a GET form along with some results from server connect queries already on my page.

Form fields: user, service

Server connect actions successfully loading: get user info, get service info.
In other words, once a user is selected I grab that user’s info in a SC action. Same thing for the service. So for example, first name, last name etc.

Since my form only has two fields, using a button to submit the form works nicely.

However, how do I go about submitting something like first and last name along with my form fields?
