Hello,
Some places to start looking:
Are you using explicit or relative paths for your links in HTML?
i.e.
explicit path:
<A href="http://www.mysite.com/dispitin.htm">
relative path:
<A href="./dispitin.htm">
Look for differences between computers on your network.
Do they all share the same router, domain, security settings, host file?

HTH,
Jeff

I'm using a Filemaker system with CDML to act as an online travel system for my employees. The problem is that although the system was working wonderfully for a few days, I now get an error akin to "the format file "dispitin.htm" cannot be found." My only problem is that the file still exists in the original location and the system still displays accurately on about half the office computers. Any ideas? I'm fresh out.

Their must be a probleme in the cdml request

try to use
fmpro?-db=xxx&-lay=yyy&-response=/folder/dispitin.htm ...

And, finally, I have been advised previously that this same error may be generated if you do not specify a "-error" page.
