On the Data Manager ----> File ---> Delete All Data
Then run it like I did in the gif I added. to the post above.
The script will create the Groups & add the groups with the ID's to the "Group" table if First Run? = true. After, it will selected all records in the Group Table, create the Global Object & then add each Group to the Global Object as an Object.
There should be no need to manually create anything in the database since the script has the Database Name & Schema in the xml file. Try closing the BAS Studio & deleting the database in C:\Users\{YOURPCNAME}\AppData\Local\BasDatabases\Database.19545. Then restart BAS.
