Hi,  
I have 20 frames on a timeline, and a mc in the frames.

frame 1 the mc is \_alpha 0%, at frame 20 the \_alpha is 100%. A tween between the frames fades up the mc alpha.

How can I change the frame 20 \_alpha setting from outside the swf file?

Say I need the alpha to be 60% at frame 20 BUT I can’t open up the FLA, can I adjust the Alpha setting (using Loadvars perhaps) without going back into the FLA? I won’t have access to the FLA (when the file is online) and I want to be able to manipulate the frame 20 \_alpha setting.  
I have tried doing this totally in actionscript and not using the timeline, but if I can’t get that to work I will need to be able to adjust the alpha parameter without editing the FLA.  
Thanks, NosferatuD2
