Problems with zerocombine task.

[Carol]

Hiiiii! I'm a new user of IRAF and I'm having some problems with zerocombine task. When I write " zerocombine BIAS*" this error appears:

ERROR: No images to combine
"pclip-pclip, grow=0)"
line 47: ccdred$zerocombine.cl
called as: ' zerocombine (input=BIAS*)'

Could someone help me??? What should I do? I really need do this reduction and I can't move on because of that problem...

Thanks!!!
