I am attempting to create a Gallery which will contain grouped Sharepoint data . However, after selecting the Gallery and attempting the following formula in Items: GroupBy(dummy_data, "Vendor Name", "DATA" ), it comes up with an error. The GroupBy doesn't seem to recognise the Vendor Name column, in the suggested options the columns are not showing up with same names as in the Sharepoint list. Instead it's names like "field 0" etc (see attached image). Any suggestions?
