[Zope] More dtml-in sequenceing and cocatenation

[hpinson@indepthl.com]

I have a statment which outputs  a sequence of form checkbox string 
pairs, from a MySQL source:

<dtml-in SQL_getMath>
<input type="checkbox" name="dance_<dtml-var sequence-number>" 
value="1" 
<dtml-if expr="'math_' + _['sequence-number'] == 1">
checked
</dtml-if>>

</dtml-in>

This does not work quite right.  What i need is to cocatenate, in the 
dtml-if expr, the string 'math_' with the number generated by 
sequence number in the loop.  Based on that evaluation, the checkbox 
is checked or not.

Any ideas on how to get this working? I can't seem to make much sense 
of the Zope Book explanation.
