I am using Character and Marge Animation in max5, and rigg is from Comet Cartoons script.
When I marge a walk that I have saved in *.anm file first time it works ok, but if I try to marge second time and use "Paste to Existing Animation" in "Marge Animation" dialog I get wrong:
"--Runtime error: Illegal self -reference in control script."
and this text:

myD = custAttributes.get $'man_handRCTRL'.Attribute_Holder 1;
if (myD != undefined) then

Can someone help me with this I have tested with simple animation on other objects and marge animation work fine.
