Answer 1

i tried making it go back the the mainpage by frame number and by label, and it actually does but the codes don't work anymore, and the codes are on top of that frame number and label name. i have the mainpage and other pages, all inside a movieclip.. called "masterclip" could that be the problem?
my buttons are inside two movieclips, could that be the problem?
im desperate for help ive been trying to finish my website for 3 months now, thats crazy!!!
thanks for the reply , i hope u can solve me problem
