I'm having some trouble displaying a table.

The original code, cgi:    $account->{transactions} = [ map { { line => $_ } } @transactions ]; where @transactions is filled with tab-separated values.

I want to display the elements of @transactions as a nice 2 dimensional table. Hence my new code, with the TMPL_LOOP:

   $account->{transactions} = [ map { { line => $_ } } @transactions ]; where @transactions is populated with array references:  push @transactions, \[$date, $type, $amount, $new_balance];

and the TMPL bit:

   <TABLE BORDER="1"> 
    <TMPL_LOOP NAME="transactions">
     <TR><TD>Transaction:</TD>
         <TMPL_LOOP NAME="line">
           <TD><TMPL_VAR NAME="date"></TD>
           <TD><TMPL_VAR NAME="type"></TD>
           <TD><TMPL_VAR NAME="amount"></TD>
           <TD><TMPL_VAR NAME="balance"></TD>
         </TMPL_LOOP>
     </TR>
    </TMPL_LOOP>
   </TABLE>

I don't know wether to look into altering the tmpl file or if my datastructure is just plain wrong?
The error appearing on the browser is the following:

Thank you!
