I have recently upgraded to 10.1 and now the a script which I wrote that worked fine in 10.0 is no longer working in 10.1.  It appears there is an issue with getting the GetParameterAsText function.  Here is there error I am getting:

Traceback (most recent call last):
  File "C:\reacch\scripts\clippedRastoGraph.py", line 6, in <module>
    polygon= arcpy.GetParameterAsText(5)
  File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\__init__.py", line 592, in GetParameterAsText
    return gp.getParameterAsText(index)
  File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\geoprocessing\_base.py", line 224, in getParameterAsText
    self._gp.GetParameterAsText(*gp_fixargs(args, True)))
RuntimeError: Object: Error in getting parameter as text

Does anyone have any idea why I am getting this error with 10.1 when everything was completely fine when running the script in 10.0?  Thank you!
