Update is not allowed

Hi there all. I have a problem with an update statement. The error we're getting starts with "UPDATE is not allowed because the statement updates view..." I know the problem is that you can't have a join in the actual update statement that fires an INSTEAD OF UPDATE trigger. The update statement looks like:UPDATE
I
SET StyleId = @StyleId
FROM dbo.Item I
JOIN dbo.ItemLinkR IL
ON IL.DivisionId = I.DivisionId
AND IL.DeptGroupId = I.DeptGroupId
AND IL.DeptSubGroupId = I.DeptSubGroupId
AND IL.DepartmentId = I.DepartmentId
AND IL.ItemId = I.ItemId
WHERE IL.ItemLinkRPriority1Id = @ItemLinkRPriority1Id
What would the appropriate statement look like to effectively run an update? We do not want to delete the trigger or alter it.

Not sure that I understand the situation - is Item or ItemLinkR a view? If so, then why not fire the update against the underlying table(s).
