Russ -

I was under the impression that [calc] would not work inside of [perl], but 
you say it worked before...  In any case, the above error message shows 
that [calc]$totalbps[/calc] is evaluating to null in your [perl] code - 
what is $totalbps and where is it assigned a value?  Perhaps assign it to a 
scratch variable just before the [perl]

[seti totalbps][calc]$totalbps[/calc][/seti]

... then put [scratch totalbps] on the page and pull it up in the browser - 
what do you see?  in the [perl] block you could do:

my $totalbps = '[scratch totalbps]' || '0';

...and see of that changes/eliminates the error messages.
