Error in Check Print form

Hi Experts .

I am working on the check print form .

i have to attach my custom script from to FBZP tcode.

It is using the standard driver program RFFOUS_C . this program is using some fields which i don't need to show on the from , i haven't use those fields.

I am executing the from through f-58 tcode.

when i check my from output through sp01 , system is generating two spool request numbers , one for my from & one for error log .

Please help , how can i remove this error .

Thanks & Regrads
