Replacing multiple statements with a loop - Syntax incorrect?

[Danger Madcow]

I have a series of images loaded in via XML and assigned to "loady" movieclips. This code works fine:

_root.myMCL.loadClip(_root.myImages[0].attributes.url,_root.loady0);	
_root.myMCL.loadClip(_root.myImages[1].attributes.url,_root.loady1);	
_root.myMCL.loadClip(_root.myImages[2].attributes.url,_root.loady2);	
_root.myMCL.loadClip(_root.myImages[3].attributes.url,_root.loady3);	
_root.myMCL.loadClip(_root.myImages[4].attributes.url,_root.loady4);	
_root.myMCL.loadClip(_root.myImages[5].attributes.url,_root.loady5);

I want to replace this with a loop since I know the total amount of items (myImagesNo), but this isn't working:

for (i=0; i<_root.myImagesNo; i++) {	
_root.myMCL.loadClip(_root.myImages[i].attributes.url,this["_root.loady" + i]);
}

Am I doing something completely boneheaded?
