Output parameter in script tool doesn't work, why?

[babakkasraei]

Hi 

I try to specify an argument for output shape file to create it (outputShape = sys.argv[4])

and to get the shape file name from parameters. Then I set the output file parameter as a feature class and output. But my output parameter doesn't work. the script is as follows. 

Why Cannot I get the output name from parameters? 

Thanks

 -------------------------------------------------------------------------------------------------------------

# the path to workplace
arcpy.env.workspace = sys.argv[1]
# The path to the CSV file
inputCSVfile = sys.argv[2]
#Get the template shapefile
templateShapeFile = sys.argv[3]
# The name of the output shape file
outputShape = sys.argv[4]    <<<-------------------------------------------------- Here???? it doesn't work,Why???   

# open CSV file
inFile = open(inputCSVfile, "r")

# create feature class
arcpy.CreateFeatureclass_management(arcpy.env.workspace, outputShape, "POINT", templateShapeFile, "DISABLED", "DISABLED", templateShapeFile)

The second parameter of the arcpy.CreateFeatureclass_management function should be a string and not a Feature Class

Great help, Thank you 

I changed the parameter value to string and it worked.
