Problem with root script when loading swf

Hi,
I have problem when loading swf files into my main fla file. I am building my portfolio site and have a main fla file that loads swf files with sliding transition effect when clicked on menu buttons. Right now I have three external swf files: contact.swf, about.swf, identity.swf.

Everything works fine if I don’t link identity.swf file, which has _root references in a code and causes problems on a main file. I don’t know how to change _root code, identity.swf works fine on its own, but distorts the timeline of the main file when loaded into the main file. I tried different codes: this., this._parent but none of them work, only _root works for me.

To be more clear I am attaching my identity.fla file with linked images.

I am just a beginner Flash user and new to actionscript, and am at my wits end with this problem. Can somebody please help me to sort this out? I would really appreciate any help.

thanks!
