hello,
I think you can try this :
http://www.ez.no/ez_publish/documentation/development/libraries/ez_template/functions/section/if_then_else_statements
http://www.ez.no/community/forum/setup_design/if_then_else_and_is_empty To see 'how to' use the if-then-else and is_empty statement.
More precise, i think that this problem has been discussed in http://www.ez.no/community/forum/general/checking_if_an_attributes_value_ie_empty
good luck.
