Trouble Joining Chamfers Along A Curve and Straight Edge

[Anonymous]

Hi,

I'm trying to add some chamfers to a part I'm working on. When I apply the chamfer, it continues through and beyond where I want it to go, instead of joining with the curved tab. Essentially, I want the chamfer to be on only the outside perimeter of the piece. 

Any idea how to do this? Thanks.
