Probelms with multitexture vertex arrays

I'm setting up two texture coord arrays in opengl for texture units one and two. I do this with glClientActiveTextureARB.

With one unit everything works fine. My initial texture displays with the proper texture coords. However, when I enable unit two rather than displaying the new texture with the first, the first is displayed again with the coords in the second texture coordinate array. I can't seem to get the second texture to display at all.

I'm sure my units are set up right because the texturing works fine in immediate mode. Below is the code I use to set up the texture arrays :

Code:

glActiveTextureARB(GL_TEXTURE1_ARB);

    glClientActiveTextureARB(GL_TEXTURE1_ARB);

    glEnableClientState(GL_TEXTURE_COORD_ARRAY);

    glTexCoordPointer(2, GL_FLOAT, sizeof(terrainVertex), &vertexList[0].s1);

    glActiveTextureARB(GL_TEXTURE0_ARB);

    glClientActiveTextureARB(GL_TEXTURE0_ARB);

    glEnableClientState(GL_TEXTURE_COORD_ARRAY);

    glTexCoordPointer(2, GL_FLOAT, sizeof(terrainVertex), &vertexList[0].s);

Can someone please help?

What textures are bound, and what texture environments are you using?

I've got textures bound to units zero and one.

Zero uses decal and one uses blend.
