MultiSample AntiAliasing using multisample FBO

I am trying to implement anti aliasing using multisampling. Here i have used FBO1(fboID) for multisampling.
I am reendering my texture image to a multisampled render buffer(colorBufID) and using it as an attachment point

for FBO. Then i have created another FBO2(frameBUfID) and blit  from FBO1 to FBO2 but i get error at glBlitFrameBuffer.

Could you please explain if the implementation is correct .
