Simple addition seems a bit tricky in zope
<dtml-call "REQUEST.set('CategoryTotal',0)">
<dtml-in "tmp.propertyItems()">
<dtml-let key="_['sequence-key']"
value="_['sequence-item']"
category="s[:1]"
counter="_.getitem(category+'Total')"> <--// Here i want to
concatenate the category from the value with the word total so that i can
lookup my declared variable in the namespace.
<dtml-var expr="counter=counter+value"> <--// Here i tried to
increase the declared variable with the value.
</dtml-let>
</dtml-in>
Can someone help?
