menu driven color changing script in a linked object?

i has added a color menu driven changing script in a couch in a 17 prim couch that i want to link together but i only want certain parts to be optional to color change but since its all linked its changing the whole thing. can someone please come to me and look at the script and tell me what exactly needs to be changed in this script?

list links_to_change = [ 3, 4, 5, 7, 11 ];
integer i;
integer n = llGetListLength(links_to_change);

for(i = 0; i < n; i++) llSetLinkTexture(llList2Integer(links_to_change, i), texture_id);

If it is a single script, it's probibly using llSetLinkPrimitiveParams and giving the argument of LINK_SET, you have two options. Either find out what the link number of each piece of the couch you want to change, and call that function with just those numbers, or you put a script in each prim you want to change color and have it waiting for a linked message from some master script that tells them what color to change.

Edit: Or what argent said

i am soooo confused i dont knows nothing about scripts
