Re: [htmltmpl] Can HTML::Template do subtotals?

Since you are stuffing the H::T loop with the dollar value for the "current month" and "year-to-date" values, why not calculate the running sub-total and stick that on the loop as well. Then in your template you can, for example, use a <TMPL_IF EXPR="__counter % 4">...</TMPL_IF> syntax to display the sub-total at every 4th position.

Having the sub-total available for each row allows the template file to choose when it wants to display the sub-total.

Subject: [htmltmpl] Can HTML::Template do subtotals?

This is my first project using Perl and HTML::Template, and my first posting to this users list (after searching http://www.bluedot.net/mail/archive/ for things like "totals" and "total row" and "subtotal").

I'm trying to figure out how to insert subtotals periodically and to calculate differences between two rows. For example, this is a mock up similar to what I'm doing (mine is more complex):

accounts              curr month    year-to-date

10-19                       $xxx            $xxx

20-29                       $xxx            $xxx

30-39                       $xxx            $xxx

sub1 10-39               $xxxxx          $xxxxx

40-49                       $xxx            $xxx

50-59                       $xxx            $xxx

sub2 40-59                 $xxxx           $xxxx

grand total               $xxxxx          $xxxxx

diff b/w sub1 & sub 2       $xxx           $xxx

Right now, I'm using several case statements in my Sybase SQL and several unions (which I know is pretty ugly)... but if I could get HTML::Template and Perl to play nicely together and let me generate occasional subtotals along the way (or differences as the case may be), that would be great. Does HTML::Template have a way to do this? I have the H:T documentation printed out (because I refer to it so often), and I'm wondering if a TMPL_IF might be the answer. But, I can't wrap my brain around how I could use it for subtotalling and differences.

Oh, and feel free to dumb it down for me since I'm new to Perl, SQL, [insert language here]. ;-)

Thanks!

P.S. I didn't include my Perl code because I wasn't sure if it would be necessary (and it's 600+ lines), but for the masochists among you, you can see it here along with the .tmpl file: http://www.perlmonks.org/index.pl?node_id=108949&user=Lori713. The .tmpl file is also included below:
