 From the docs on Updating Database Tables with a From (I really don't know 
how relevant this is anymore):

mv_data_enable (scratch)

\IMPORTANT: This must be set to a non-zero, non-blank value in the scratch 
space to allow data set functions. Usually it is put in an mv_click that 
precedes the data set function. For example:
             [set update_database]
             [if type=data term="userdb::trusted::[data session username]"]
                 [set mv_data_enable]1[/set]
             [else]
                 [set mv_data_enable]0[/set]
             [/else]
             [/if]
             [/set]
             <INPUT TYPE=hidden NAME=mv_click VALUE=update_database>
