Replacing multiple statements with a loop - Syntax incorrect?

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

Code:

---

_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:

Code:

---

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?

this["_root.loady" + i]

replace with:
_root["loady" + i]
