Blend Shapes And Weighting

Hello everyone-

I'm a new guy here and hopefully someone can help me with this problem. I am rigging a bird, I created a blend shape for the beak so it can move its mouth. My problem is when I smooth bind the geometry as soon as I go to edit the weights, the blend shape stops working all togethr. I've tried everything I can think of, including remodeling the shape, please let me know if anyone can help. Thanks a ton

are You weighting blendShape or skinCluster?

When I weight the beak blendshape it messes up. The weird thing is I have blendshapes for the eyes as well and when I paint them they work fine, thanks for your reply.
