Evaluate javascript is failing

Hi Team,

I am facing issue in AJAX TRUCLIENT IE, I am using LR 12.02 and IE 11 for developing my vugen script in my application I have a dropdown list where I need to parametrise the values in the list, I have been using 

window.pDivison=LR.TC.getParam("pDivision") in my javascript but when i replay my script, this Javascript fails and shows the ERROR as API_UNEXPECTED_ERROR parameter or attribute not defined. 

If I replay in the replay layout MERR 205177 is shown.

also when i try to record login action in INIT and rest of the actions in ACTION block and replay it ,INIT is executed succesfully and ACTION block asks for user to login again(Flow is not maintained).

Sometimes when I replay my script the cordinates are missed. Any help on this issue is much appreciated.

Thanks,

Madhu
