How to the add the current resource template name to a snippet call [SOLVED]

Hi Guys

so basically I want to do a snippet call like...

[[snip_name? &template_name=`********CANT WORK OUT WHAT TO PUT HERE**********`]]

where template name would the the template name of the current resource it is called from.....

The snippet will then return content specific to that template

Thanks

Note it returns an integer
