I want to variablize the size parameter as I have done below

<TR> <TD VALIGN="TOP"> <STRONG><!--#var fieldName--></STRONG> </TD> <TD VALIGN="TOP"> <i><!--#if "_.has_key(fieldID)"--><!--#var "_[fieldID]" size=fieldSize etc="..."--><!--#/if--></i> </TD> </TR>

It seems however that I get the error "a size attribute was used in a var tag with a non-integer value.". So it appears to me that this can't be done. Is that so?

Is it a property on a DTML Document or Folder? If so, you can specify it as being a integer, instead of a string.

If the variable came from a form, you can add :int to the name on the form (filedID:int) so Zope will cast it to an integer. This will make the variable required, however.

You could also convert the variable to an integer on the spot, using _.string.atoi, like so (untested):

<!--#var "_[fieldID]" size="_.string.atoi(fieldSize)" etc="..."-->

Sorry, I should have specified. Its coming from a namspace ie <!--#with "_.namespace(fieldSize=3)"--> Which I'm presuming would keep fieldSize as an int?
