User Discount Problems

******    message to minivend-users from mwatkins@lexmark.com     ******

I currently running minivend version 3.12beta6 and have been
working on a way to give an individual a discount.  The userdb
has a column added called getdiscount.

The following code is from basket.html:
[item-list]
.
.
                [if session logged_in]
                        [if value getdiscount]
                                [calc]
                                $myper{""} += 1 - ([value getdiscount]/100);
                                return '';
                                [/calc]
                                [discount [item-code]]
                                return ($s * $myper{""});
                                [/discount]
                                <FONT COLOR="#FFFF80" SIZE=-1>User gets a
             [value getdiscount]% discount!</FONT>
                        [/if]
                [else]
                    [discount [item-code]] return($s); [/discount]
                [/else]
                [/if]
        </TD>
        <TD [var HEADERBG] VALIGN=TOP ALIGN=RIGHT>
                <FONT COLOR="__HEADERTEXT__">[item-subtotal]
                </FONT>
        </TD>
</TR>
[/item-list]
The basket total shows up exactly correct.  If I change the number in userdb
the total work fine.  HOWEVER, when I proceed to the checkout page.
I get the following:
          Durr-Walks in Beauty
         Giclee                                       1 @ $320.00
                  $320.00
                                                                   Subtotal
                        $0.00
                                                                 Sales Tax
                       $0.00
            Shipping (includes $3  handling charge)                      $6.93

                                                                        TOTAL
                     $6.93

BUT if I put the following in for [discount]:

[discount [item-code]]
return ($s * 0.9);
[/discount]

Everything works like it should, checkout is fine the totals are fine!
What am I missing it has been driving me nuts!

Thanks in advance!
