ActionScript 3.0 :: Loading External Data To Array (Syntax Error)

I'm trying to load data from an external text file into an array. I created an array and am able to load the data into an array if I explicitly say something like:
ActionScript Code:
array[0] = event.target.data.uid1_name;

I can then do a trace statement on array[0] and it will output the correct name from the file. My problem is I'm trying to iterate through the variable names in the text file in the file by using an index variable. This is the code I'm using after doing all the URLloader, URLRequest, and so forth stuff:
ActionScript Code:
for(var i = 0; i<20;i++){
fArray[i] = event.target.data.uid[i]_name;
}

This produces a syntax error. I've tried several other syntax variations but haven't been able to figure it out. Why syntax iterate the number after uid (uid1_name, uid2_name, uid3_name, etc)?
