Article Number for Electronic Reference

when i cite an electronic article, i cannot get the article number to show up, even though i have entered it into my endnote database. everything else regarding the reference looks good.

this will depend on the output style you are using and whether this field is included in the template for the electronic reference type – if it even exists in the templates for that style.  If it doesn’t, it will use the “generic” template which may not have the correct field included for this.  

What output style are you using and which ref type have you assigned to the record(s) in question.
