cannot get cfformitem to use type script

Hi I'm using cf version 7,0,0,91690      

my cfform works fine but I anted to add colour to the rows based upon a value in the query

when I add cfformitem to the .cfm and run, the browser via cf reports that the cfformitem cannot be "script"

is it my installation version causing this ?

or how can I get cf to use type = "script"

thank you in advance
