Dear Sir:

I am trying to write the syntax to run conjoint analysis using PASW 18.00 and every time I run the syntax I get this error message

" Warnings Text: file Command: conjoint The filename is not valid. Execution of this command stops." 

This is the syntax I wrote:

conjoint plan 'c:\planfileanterior.sav'
/DATA ' c:\datafileanterior1.sav '
/SCORE= score1 to score9
/SUBJECT=uniqueid
/FACTORS=age (DISCRETE)
cooperation (DISCRETE)
insurance (DISCRETE)
/PRINT SUMMARYONLY
/UTILITY=file
/PLOT=SUMMARY

And this is a study to explore general practitioners' preference to the use of certain dental procedure with children in their offices.My design is 3X3 and I used 
the reduced fractional design with 9 scenarios to present to my audience. 

Can somebody help me in this?

Thank you very much,
Elham
