Interstate custody issue...?

okay so back in april i enlisted in the army reserves and had been caring for our daughter since my husband and i split back in june 09.. he took summers with me having school years (verbal agreement) .. may 2010 in nj court court granted him that summer and this one exception of the school year so i could fulfill milit. obligations. i went down to arkansas where the father has been residing since our split in 09 and 48 hrs until me and our lil girl were to fly back home to jersey (where she's been residing for the past 3 to 4 years school, extensive family on my side) he hit me with an emerg. custody order from arkansas! The courts here in nj are telling me they don't have jurisdiction since she's been there more than 6 months... that was the whole reason of going to court back in may 2010 before he took her for the summer, and i was granted primary residential custody having joint custody between us. He is angry because i didnt want to stay in Lil Rock and also filed for divorce even tho we've been seperated for over 2 years already! Is it possible for the transcripts from our court hearing to be legally binding in the Arkansas jurisdiciton? Besides that, he's got extensive mental instability, substance abuse which i found out he's been in outpatient rehab on suboxone for the last year while having our child, and the living conditions he has her in are not up to my standards.. he shares a bed with her (she's 6) because she said she wanted to!! He also told his court he's unemployed but works at a place called Cupid's and at times when he can't find a sitter, he brings our minor child into the store and she hangs out in the back on the computer...still very much subjected to the obsenities throughout the store. I feel my court is doin me dirty and i can get all sorts of proof as far as terrible things he'd done prior to our split and him moving back in 09 .. arrests, crisis center stays and substance abuse then and restraining orders for fear of our lives. I just wanna know what do i have to do to get my lil girl back to her rightful home? Hes gotten a lawyer involved on his side. Iv been the main caretaker and constant in our daughters life since birth and he's using her as leverage so it seems to me.
