[Tclhttpd-users] ?? cgi error

[dlb <sem...@wo...>]

I've just set up tclhttpd3.2 from the most recent distribution available on
sourceforge and , when testing the CGI examples provided, I'm running into the
following errors.
This is on a win98 , the standard library (tcllib 0.7) is installed.

for instance when attempting to 'dump the environment'  I get.

Tcl-Webserver/3.2.0 October 12, 2000
Tcl version 8.3.0
error info =
can't use empty string as operand of "+"
    while executing
"expr {$counter(total) + $delta}"
    (procedure "counter::count" line 3)
    invoked from within
"counter::count $what $delta"
    (procedure "Count" line 5)
    invoked from within
"Count cgihits"
    (procedure "CgiSpawn" line 26)
    invoked from within
"CgiSpawn $sock $path"
.
.etc..
.

the error is the same for all of the tests I've done.
Any advice ?

thanks
David
