I'm need some legal help for a father in jail for non pymnt of child sup.in Ind. but paying order in illinois.?

My husband had been stopped for a traffic violation and was taken to jail in illinois for non payment of child support in indiana. His children do live in Indiana now but we didn't even know there was a court order to pay in indiana we have been paying to Illinois under the original order. Now indiana wants 5000 to release him....if we had 5000 we would have paid the back child support along time ago. How can there be two court orders for child support? How do I get my husband out of jail without the 5000?
