I really need help with some buttons please

Hello everyone. I am very new to ActionScript. I just normally used Flash for art work and small movies. And I thought buttons were the easiest.
Here is my problem. I am doing a website for my band. I did the whole tutorial on loading external SWFs and making transitions. The file I teated worked fine so I decided to add some script to the loaded SWF file. For some odd reason the buttons don’t work after the file is loaded. But when I test the loaded SWF seperately they work great.
What am I doing wrong? Do I have to control all the actions in the loaded SWF from the main movie that it is being loaded into? Or is there something I am missing? Any help would be most apprecited
