Using MultiValue in Python script tool parameters?

My script works fine with a single feature class selected for clip_fc = arcpy.GetParameter(0) .

However when I set clip_fc to MultiValue in the script properties and then select several feature classes, I get an error "Parameters are not valid.".

Can anyone show me where I am going wrong?

import arcpy import os.path from arcpy import env arcpy.env.workspace = r"C:\GIS Home\project_1\clipshps\Combined_mf.gdb" arcpy.env.overwriteOutput = True clip_fc = arcpy.GetParameter(0) clip_name = str(clip_fc) output_dir = r"C:\GIS Home\project_1\clipshps\outputs_clip" for fds in arcpy.ListDatasets(): for fc in arcpy.ListFeatureClasses('','',fds): out = os.path.join(output_dir, fc + "_" + clip_name[40:] + "_clip.shp") arcpy.Clip_analysis(fc, clip_fc, out, "")
