Door wont open any more HELP!!!!!

[Bam Bam 56]

i have been rebuilding the passenger side of my truck, lower front door pillar, front floor support and floor panel is what i have done so far. I decided to make sure the door fit before i went forward with installing the new inner and outter rocker panels. at first the door would stick out about 1/8 inch when closed, i slid the door forward and had the same result. so i tried sliding the striker plate up. Now the door closes and has perfect gaps and body lines. The down side, the door doesnt open any more. I puch the button on the door handle and i here it disengage, but the door is stuck closed.

Any advice out there?
