SetTexture in linked prims. How I do that?

Hi.. I have here a code that will change the texture once I touch the prim. But I have a problem when I copied it and link it, the SetTexture function will not work as a whole object.

default
{
    state_entry()
    {
    }
    touch_start(integer total_number)
    {
        integer number = llGetInventoryNumber(INVENTORY_TEXTURE);
        float rand = llFrand(number);
        integer choice = (integer)rand;
        string name = llGetInventoryName(INVENTORY_TEXTURE, choice);
        if (name != "")
        {
            llSetTexture(name, ALL_SIDES);
        }
    }
}

How will I script of a linked prims using llSetTexture function? Thanks in advance.

llSetLinkTexture

Thanks, it solved my problem.

Trying to use that script. Why doesnt it work? I changed llSetTexture to llSetLinkTexture, but i get an error when compiling. - ERROR: Function call mismatches type or number of arguments.

thanks for helping...

You need to add a prim number:

llSetLinkTexture( link_number, name, ALL_SIDES );
