Yes, it has it's own behaviour ID and, the Risk ID is directly linked to whether the behaviour is low, medium or high, therefore has a different Risk ID.
If all of the risks were on one form, there would be up to 57 (possibly more if future versions of the form add more), which would make it harder for the user to find the one they are looking for. Also, the original form which is completed by the assessors (attached) breaks the behaviours down into at risk (low), medium and high risk. I felt that having the Access forms displayed in a similar way would allow the user to input the data on the forms, into the database easily (assessors are not the same as users).
