Hi will these be possible?

Obviously these is an incorrect tal expression (the replace one) but there are any way to create an expression like these and correct?

You can use the TAL "on-error" handler: <tal:b tal:replace="python: dictionary['value1'][5]" tal:on-error="string:Value not available" /> see also your TAL online help: http://localhost:8080/Control_Panel/Products/PageTemplates/Help/tal-on-error... Michael -- http://zope.org/Members/d2m
