Query String on SSI and Apache?

[Ken]

Hi.

I am currently using an SSI call to a simple script to display an image passing it a paramater of pos() to indicate the position it should appear in a list of images.

Problem is, it works fine using Zeus Webserver but running the exact same ssi call under Apache it fails with the error
Invalid CGI ref
Anybody got any ideas?

The actual call is:
<!--#exec cgi="/cgi-bin/banners/get_banner.pl"-->

Or at least it SHOULD read:

<!--#exec cgi="/cgi-bin/banners/get_banner.pl?pos=1"-->

Doh!
