Hi  hopefully there's an easy fix to this  - I think there will be  I have three tables A, B, C

I am running a select statement from table B.

I left join to table A on a common variable (taskgroup_id)  all good

I left join to C on a common variable  but because this variable is in all 3 tables (i thihk this is why)  I am getting an error "Column 'division_id' in from clause is ambiguous "
