Create list from dynamic array

Im having trouble creating a list from my array results.
I have my array being populated through flash vars
file=tvv.flv, test.flv, video.flv

this.Array = new Array(_root.file);
this.Array = _root.file.split(", ");
totalvideos = this.Array.length;

for (var i=0; i<totalvideos; i++) {
filechecker = this.Array*;

Where filechecker is a text box on the stage, set to html + multiline

The only result is the last file in the array

Any ideas anyone?
