Script error in IE v7.0.x for progress bar widget


Hello All,
I am using a progress bar in my jsp and when I access it in IE , it is
giving me script error when it tries to set new progress value to
progress bar.
This functionality works perfect in Firefox but I could not resolve
this script error for IE. I have tried setting values in different
ways but still its not going away.
Error info :
Invalid argument.
Line:12
Col : 12949
File : jquery-1.3.2.min.js
Code snippet:
$("#progressbar").progressbar("option","value",progress);
I am getting progress from some other code and then calling above code-
snippet to set the progress to progress bar.
I will really appreciate any pointers that will help me fix this.
Thanks in advance,
Vivian
