Need a little help with a custom button directing User to a custom email template. My Leads button works like a champ but the same button in Contacts refuses to play nicely:
This (Leads) button works just fine:
... but ...
This (Contacts) button is essentially the same but throws an error no matter what changes I make to it:
the error thrown is :
URL No Longer Exists
Am I missing something obvious here? Where should I be looking to resolve this URL error?
