External swfs not working properly

Hello- I’m looking for some help with changing the scrolling menu whenever a user clicks on a navigation button to go to another set of thumbnails in my flash gallery. I combined the ideas from this tutorial>> http://www.kirupa.com/developer/mx/full_site.htm and this one>> [url=“http://www.layoutgalaxy.com/html/htmnewletter41-page1.htm”]http://www.layoutgalaxy.com/html/htmnewletter41-page1.htm. Though I made a few changes to the gallery tutorial with help of someone from another forum. By adding some arrow buttons (next and previous buttons) to the left and right of the main loading screen. For some reason whenever I try loading this gallery as an external swf file into another fla file- I experience some problems. I’m thinking it may have something to do with the actionscript I added to the buttons. In case that’s the issue here is the script>>

The script for the next and previous buttons (near the loading screen) is>>>

on (release) {
loadMovie(“clip”+(_level0.current_clip+1)+".swf", “_root.screen”);
_level0.current_clip = _level0.current_clip+1;
with negative values for the previous arrow/button.

The script on each thumbnail (button) is>>

on (release) {
loadMovie(“clip4.swf”, “_root.screen”);
_level0.current_clip = 4;

The fla file I’m using to load the external gallery file has two layers one named Actions and another named Navigation (as mentioned in the tutorial). The Actions layer holds the movie clip instance named content and the actionscript>> _root.content.loadMovie(“main_content.swf”); The Navigation layer holds simple nav buttons “Goto Menu1” and “Goto Menu2” .

Anyway when go ahead preview publish this fla file, the external swf loads though none of the buttons work. I also tried loading the screen or the thumbnail scroll by themselves and the same thing happens- NO button control… And for some reason I don’t receive an error message when I do a publish preview. Though if I preview the fla files (the external files) of a thumbnail scroll menu by itself- it works fine.

Does anyone know what could be happening? How do I go about fixing this?

Thank you.
