Wanted, Next/back script.

What I am looking for is just the "next" or "back" script that you find in the many vendors left and right prims. All you do is click on it and it goes to the next/back to the pose that I want to view. I'm creating a modeling stand for my models.

It's easy ;p

string gCurrentAnimation;
 list ANIMATIONS = [];
 integer gListLength;
 integer gIndex;
 changeAnim(integer num) {
 	if(num) {
 		if(gIndex != 0) {
 			gIndex -= 1;
 			stop&Start();
 		}
 		else {
 			gIndex = gListLength-1;
 			stop&Start();
 		 }
 	}
 	else {
 		if(gIndex != gListLength-1) {
  			gIndex += 1;
  			stop&Start();
  		}
  		else {
  			gIndex = 0;
  			stop&Start();
  		 }
  	}
 }
 start&Stop() {
 	llStopAnimation(gCurrentAnimation);
 	gCurrentAnimation = llList2String(ANIMATIONS,gIndex);
 	llStartAnimation(gCurrentAnimation);
 }
default {
	state_entry() {
		gListLength = llGetListLength(ANIMATIONS);
	}
	changed(integer c) {
		if(c & CHANGED_LINK) {
			key avatar = llAvatarOnSitTarget(); //Or something like that
			if(avatar != NUL_KEY)
				llRequestPermissions(avatar, PERMISSION_CHANGE_ANIMATION); // Or something like that
		}
	}
	run_time_permissions(integer p) {
		if(p & PERMISSION_CHANGE_ANIMATION) { //Or something like that
			gCurrentAnimation = llList2String(ANIMATIONS, gIndex);
			llStartAnimation(gCurrentAnimation);
		}
	}
	touch_start(integer num) {
		if(llGetLinkName(llDetectedLink(0)) == "right")
			changeAnim(0);
		else if(llGetLinkName(llDetectedLinkNumber(0)) == "left")
			changeAnim(1);
	}
}

ERm. Ok. I jsut wrote that on the spot, so it might be wrong, and I didn't include the animatons and anything else you want, but I pretty much wrote your script minus the build. (I just wrote it on the forums so if it has a syntax error you can IM me and I will fix it for you.)
