Multiple mc's on 1 var...I must be stupid

var target_mc:MovieClip = _root.sequence;

thats what I got atm, but what i want is that it targets 2 movieclips
I tried things like this

var target_mc:MovieClip = _root.sequence + _root.sequence1;

even tried adding var but nothing worked, what the hell am i doing wrong…its been 3 years ago since ive used flash and it made me an absolute retard or something :stuck_out_tongue:
