indentation - Python indent error AFTER statement -

i keep getting unexpected indent error in python idle, oddly, me, it's after statement. checked in notepad++, , tried deleting spaces , manually adding 4 in, i.e. not tab. below code; error highlighted after field_value statement. suggestions appreciated

i

import arcpy, sys  arcpy.env.workspace = "c:\\" shapefile = "uscancer2000.shp" field_name = "friday"  #add field arcpy.addfield_management(shapefile,field_name,"long", "","","","","nullable","non_required","")  cursor = arcpy.updatecursor(shapefile)  row in cursor:     #get value of each of our fields, , put them variables     c1 = row.getvalue("cnt1")     c2 = row.getvalue("cnt2")     c3 = row.getvalue("cnt3")     p1 = row.getvalue("pop1")     p2 = row.getvalue("pop2")     p3 = row.getvalue("pop3")      #check missing values, assuming non-missing values greater or equal 0     try:          if((min(c1,c2,c3,p1,p2,p3) < 0) or ((p1+p2+p3) == 0) ):  t             field_value = 0         else:             field_value= 1.0 

the error after field_value= 1.0

it should be

else:     field_value = 1.0 * (c1+c2+c3)/(p1+p2+p3) print "done"
