help - "access not supported" #backdrop.

[gtawebb]

I am working with a w3d file created in Maya and exported into director. In order to make my 3d shockwave file seem backround transparent (yet maintain performance) i wanted to export an image plane with my scene into Director. The image plane would not export. Oh well i'll have to create one in Director using the backdrop command( i thought). However, I keep on receiveing the error message "access not supported" #backdrop. Below is the code I used, can anyone help me or advise me on the meaning of this error message.
-member("eye&quot.newTexture("interface_backround",#fromCastMember,member("interface_backround&quot)
-sprite(2).camera.backdrop[1].source = sprite(2).member.texture("interface_backround&quot
