Issue with 2 bump maps

[Zvi]

I use two Bump maps in the same object, one has a texture that covers the entire object, and the other has a logo. Now the two maps fit together, but I want the map with the logo to cover the texture map so that where the logo is  visible, you will not see the texture.
