Problems with cgi

["Zeppelin Inc." <zeppelin@neo.lrun.com>]

Have a few cgi programs that I am trying to get to work the problem is with
the - caracter
line like img src="/cgi-bin/counter.exe?-fh00f+-dhome+index.htm
if you take out all after the ?  so it reads 
img src="/cgi-bin/counter.exe?index.html 
it works but you cant send any arguments to it to change settings am I
missing something? or is this because it won't let the - caracter through?
thanks for any help you can give 

also reply by email if you want
