Dynamic scrolling text only displays bout 40 lines

Hi everyone,
just a query about a text file i am loading into a scrolling dynamic box. It’s a fairly long list of subcommittees i need to include in the site for an assignment. Everything works but it only displays about the first 40 lines of the .txt file.
My actionscript is-

loadText = new loadVars();
loadText.load(“grouplist.txt”);
//creating the loadVarsText function
loadText.onLoad = function() {
scroller.text = this.grouplist;
};
stop();

Would appreciate any pointers or advice.
Thanks(-:
