Hi, I need to display a particular google map (not the standard one) for my accounts in Zoho CRM.

I think, am I wrong?, I should use a widget (it's an HTML page with some javascript) so I made one that displays the map the way I need and it works BUT the content is static (an hard coded address) while I'd need it to be the address of the Account record active when the widget was called (more than one field is involved: Billing Address Street, City, Code and Country; I guess the resulting string must be formatted to be compliant with google maps specifications). How can I do it?  

Thanks in advance.
