set in multiple progressive variables

[narx]

I'm still asking for help
I need to assign variables
number1 number2 number3 etc.
the various lines I'm reading from a file
with the part highlighted in red does not flee

(defun contarighe ()
(while (/= row nil)
(setq line (read-line myfile)
(progn)
(princ number)(princ ":")(princ line)
(whether)
(setq counts (+ counts 1) number (strcat "number:" (rtos counts) ) ; row number
(princ)
) (setq (strcat "number" (rtos count)))
(close myfile)
[Bleep] [Bleep] [Bleep [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep]
(getkword "You've been through contarigues")
)

Can someone tell me why? . .
thanks in advance
