Help
Hey guys, i'm just trying to get this to work here.
I need the nextItem() and itemBrowser() to talk to each other, and exchange the value of the selected item, and same with prevItem() and itemBrowser(). Basically when i click the button for next item, i need it to pass the selected item from browser, to next or prev, (based on the button) edit the selected item number and pass that number back to the browser. After that, it's all peachy. I was pullnig my hair out on this for 6 hours last night. Any input? i've included all 3 class files. TY!
