Which interface in Sage 500 are you using?

How to check the interface? Please guide.

Where are you in the Sage 500 application? The "location name" doesn't tell us what action you are performing or what you are doing to get there.

 
FYR; I want to change the unit (Location) name but couldn't save.  

Secondly Please guide how to contact with Sage Intacct support team for live chat?

This forum is for a different product line, Sage 500, not Sage Intacct.
