Is there a simple multi-vendor script available to put inside your own mesh?

[Whystler]

Hi there

Can anyone recommend a multi-vendor script that will do this?

-I want to provide three prims that are linked: root prim, and two arrow prims.
-The root prim holds all of the items, and all of the textures representing each item.  When clicked, it gives the option to pay the amount appropriate to the item shown.
-the arrow prims change the texture (forward or back) of the root prim's changing face, and make the corresponding product (to the picture) available for purchase when the root prim is clicked.

It's important that I be able to provide my own prims/meshes to put the script(s) into, because i want to be able to customize it.

On another level, it would be helpful if the script was full perm so that I could one day set the meshes I make for the vendor for sale in the marketplace.

Thanks for your help, if this is possible
