[Zope] Expression Evaluation Problem (Newbee Question)

[Sam Gendler]

Assuming you have <input type="checkbox" value="1" name="xtype">, then your if
statement needs to be <dtml-if "xtype=='1'"> (note the extra single quotes),
which does a string comparison.  Otherwise, you are comparing the ascii code of
'1' with the ascii code, 1.  They don't match.  Alternatively, you could put
<input type=checkbox value="1" name="xtype:int">, which will force the form
field to be cast into an int.  Or else you could have <dtml-if
"_.int(xtype)==1">, which explicitly does the cast for you.
