[mv] Using Scratch Variable as Pointer

[Eric Paul <epaul@spellbook.net>]

Is there any good reason that you can't use a scratch variable as a pointer 
into a database?  I'm trying to parse this code under Minivend 4.04a and it 
is returning nothing.  Assume that all the proper entries do exist in the 
database.

[seti product_category][data
                                 table=master
                                 col=category
                                 key=`
                                         $tmp = q{[my-code]};
                                         $tmp
                                 `]
[/seti]

[data
                 table=cat
                 col=banner_text
                 key=`
                         $tmp = q{[scratch product_category]};
                         $tmp =~ s/[ ,].*//;
                         $tmp
                 `]</B></FONT></TD>

I can display the contents of [scratch product_category] and get the proper 
category field.  I then try to do the lookup in the cat database to get the 
proper text, but it always returns nothing.  Am I doing something wrong, or 
can you just not use scratch variable in this manner?
