Mike,

I've traced the looping problem to the following bit of code in Data.pm (in 
the chain_cost subroutine):

#       if($raw =~ /^\[\B/ and $raw =~ /\]$/) {
         if($raw =~ /^\[/ and $raw =~ /\]$/) {
                 my $ref = Vend::Interpolate::tag_calc($raw);
                 @p = @{$ref} if ref $ref;
         }

I don't think that the regex /^\[\B/ can ever match anything, so I've taken 
out the \B.  That fixed the endless looping.

But, now we pass a string like "[do_ups weight=18 mode=Ground adder=0]" to 
tag_calc, which completely chokes on it.

It products an error in the log file like:
host2.axion-it.com acNCVX3N:axion-it.com - [17/June/2000:22:31:19 -0400] 
cac /cgi/cac/process.html Safe:
  syntax error at (eval 177) line 1, near "18 mode"
 >
 > [do_ups weight=18 mode=Ground adder=0]

I'd have to guess that Vend::Interpolate::tag_calc is not the right routine 
to parse and interpolate this kind of string (or even a more complicated 
one like "[do_ups zip=[value zip] weight=18 mode=Ground adder=0]" which is 
what I started with).

The routine "interpolate_html" might be appropriate, but I don't know if it 
returns the correct data structures or what else might break with this kind 
of a change.  At this point, I'm way out of my depth.

Any suggestions?

Thanks.
