Loading external txt files question

Hi guys. Here is my problem:

I can get external txt files to load into a dynamic txt field using action script on a button. But what I want to do is have the external txt file load immediately into an mc, or dynamic text field, without the visitor actually having to press on a button. I’ve searched the forums and tried many different things in flash, but I am still a bit of a novice with the program, and haven’t had any luck.

Any insight?

Thanks.
