I use the following expression in one of my databases. It cribs stuff from a post originally put up by Raybaudi:
<body bgcolor='#FFFFFF' TopMargin='0' style='border:0'>
<iframe width='" & GetLayoutObjectAttribute ( "MapViewer" ; "width" ) - 40 &
"' height='" & GetLayoutObjectAttribute ( "MapViewer" ; "height" ) - 30 &
"' frameborder='0' scrolling='no' marginheight='0' marginwidth='0'
src='http://local.google.com/maps?q=" & CustInfo::Street & "," & CustInfo::City & "," & CustInfo::State & "," & CustInfo::Zipplus4 & "&output=embed&iwloc=0&z=14'>
The blue text refers to actual fields in the current record of my database so you'd need to edit that portion to refer to fields in your own database.
OK, this is a good solution. But how do you make a simple map like that which has MULTIPLE ADDRESSES?
I have a feeling that the WebViewer is doing something weird with the encoding, but I have no idea what. Is there a solution to this problem?
