What directory are your PowerCMS files and folders in on your remote site?
If it is in a folder called 'CMS' in the root of your remote site, then your WA_Globals.php would look like:
$WAGLOBAL_Site_Name = "Your Site Store Name" ;
$WAGLOBAL_localRoot = "/WA_CMS/"; //relative path to your PowerCMS files on your local testing server.
$WAGLOBAL_remoteRoot = "/CMS/"; //relative path to your PowerCMS files on your remote server.
// Admin Settings
$WAGLOBAL_Admin_UserName = "yourAdminName" ;
$WAGLOBAL_Admin_Password = "yourAdminPassword" ;
On the WA_Globals.php file uploaded to your remote server, you may as well put your remote CMS folder name as both the $WAGLOBAL_localRoot and $WAGLOBAL_remoteRoot names.
The globals file is the same in Version 102 as it was in 101.
