search not working

I tried using the site search facility but get the following message

Active Server Pages error 'ASP 0126'

Include file not found

/search.asp, line 3

The include file 'CYiderSearch.asp' was not found.

This is with Safari, Firefox & Camino.

I cant try with a windoze PC until tomorrow. Has anybody else had a problem?

Works fine here, both with Firefox and Opera on W2k.

..and fine here, with IE6.
