tk_bakeParticleInstancer 1.4.0 for Maya (maya script)

Hi, after creating shelf button as suggested and executing it, I get the bellow errors without the gui-window showing up; if I source the script then the gui-window shows up but then get another error listed further below.

Errors from shelf button:

// Error: $tmpRot = `getAttr ("dup_" + $id[0] + ".rotate")`; //

// Error: "$aimWorl" is an undeclared variable. //

// Error: $tmpRot = `getAttr ("dup_" + $id[0] + ".rotate")`; //

// Error: "$tmpRot" is an undeclared variable. //

// Error: setKeyframe -at "rotateX" -v $tmpRot[0] -time $frame $dup[0]; //

// Error: "$tmpRot" is an undeclared variable. //

// Error: setKeyframe -at "rotateY" -v $tmpRot[1] -time $frame $dup[0]; //

// Error: "$tmpRot" is an undeclared variable. //

// Error: setKeyframe -at "rotateZ" -v $tmpRot[2] -time $frame $dup[0]; //

// Error: "$tmpRot" is an undeclared variable. //

// Error: delete $constraint; //

// Error: "$constraint" is an undeclared variable. //

 

Error from sourcing script:

// Error: Cannot find procedure "tkSelParticles". //

 

I would greatly apreciate some help to get this tool working in maya2011.

 

thanks,
