When you say, "I consent to the following order," you should include the order that you would agree to, or the order that you want. Let's say the movingparty is requesting visitation every weekend. You may not consent to this as an order, but you would consent to the following order, "visitation every other weekend." You will use the Supporting Declaration to explain your position in detail, but use the form FL-320 to state an abbreviated version of the order you want.
Generally, as for child support, you would only fill-out this information in your response if the moving party has included it as an issue for the Order to Show Cause. Regardless of the open DCSS case, you have to respond on the FL-320. It's not necessarily a question of jurisdiction. You would respond on the FL-320 form with something like, I consent to guideline support.
You can also set-up an appointment with the Facilitator's Office to help you properly reply to the OSC.
