RE: MV3:12 Discount Help Needed/ Gift Certificate

How can I get the discount variables to scope correctly?  I've tried using
the [set] and [scratch] methods, but can't get that to work.

Here's an example of something else I tried:

[set currbal]
[data base="userdb" field="balance" key="[data session username]"]
[/set]
[perl]
if ([subtotal] > [scratch currbal])
{
[set discamt][scratch currbal]
}
if ([subtotal]<[scratch currbal])
{
[set discamt][subtotal][/set]
}
[/perl]
[discount ENTIRE_ORDER]$s-[scratch discamt][/discount]
[/if]

This just returned errors like this:
xxx.xxx.xxx.xxx 3gyda9C4:xxx.xxx.xxx.xxx - [04/May/1999:09:45:25 -0700]
newcb /shop/
newcb/ord/basket Discount ENTIRE_ORDER has bad formula. Returning normal
subtota
l.
> Can't locate object method "scratch" via package "discamt" at (eval 95)
line 1

Any more clues?

Your variables are not scoping correctly - I imagine that inside a [calc]
routine minivend will assume the variables to be local.  ??
