Child Support question?

I owed back child support for a couple years because i didnt work, i lived with and took care of my grandmother. I am paying now, and theyre taking out quite a bit...fair enough. Now i have a court summons saying that I'm being sued for lack of payment. I want to try to re-schedule it because i may not be able to afford the bus ride out there...its hours away. Now, my question is...whether they reschedule it or not, when i arrive at court, are they gonna most likely arrest me on the spot, demand a full payment on the spot (approx. 9,000 dollars)...or will they give me some time to pay it off?, seeing as how i am paying it off now, slowly and surely
