[LLDialog error. Buttons cannot be more than 24 characters long.]

Ok, thank you very much for your help. Getting a syntax error at the 

 

if (~idx)    part, but I think I'm beginning to understand. Thank you so much for your help.

[LLDialog error. Buttons cannot be more than 24 characters long.]

Thank you very much. However, I'm a bit confused on how to add this into my script, so that I can have it do what it does now, which is look at the items in the inventory, generate a list, and then when I click on the button, it rezzes the object .5 meters above the container. I keep getting syntax errors, or in one case, the script compilied, but then wouldn't run at all. I'm VERY new to scripting, so a lot of what you said went over my head, to be honest. I'll keep plugging away at it, but if you could perhaps "dumb it down" a bit for me? I'm still learning.

 

If not, I still greatly appriecate the time you did take. Numbered buttons won't work for what I'm doing, but I did bookmark that link for further reading.

Hey, been working on a frankenscript to generate a menu, read the objects, and then rez the selected object right above. Problem I'm running into is I have some items that arent mod, so I can't reduce their names to less than 24 characters. I would be greatly appreciative if someone could help me with the llgetsubstring, or how to truncate the names so I can use this script.

 

list MENU1 = [];
list MENU2 = [];
integer listener;
integer MENU_CHANNEL = 1000;
 
 
Dialog(key id, list menu)
{
llListenRemove(listener);
listener = llListen(MENU_CHANNEL, "", NULL_KEY, "");
llDialog(id, "Select one object below: ", menu, MENU_CHANNEL);
}
 
default
{
on_rez(integer num)
{
llResetScript();
}
 
touch_start(integer total_number)
{
integer i = 0;
MENU1 = [];
MENU2 = [];
integer c = llGetInventoryNumber(INVENTORY_OBJECT);
if (c <= 12)
{
for (; i < c; ++i)
MENU1 += llGetInventoryName(INVENTORY_OBJECT, i);
}
else
{
for (; i < 11; ++i)
MENU1 += llGetInventoryName(INVENTORY_OBJECT, i);
if(c > 22)
c = 22;
for (; i < c; ++i)
MENU2 += llGetInventoryName(INVENTORY_OBJECT, i);
MENU1 += ">>";
MENU2 += "<<";
}
Dialog(llDetectedKey(0), MENU1);
}
 
listen(integer channel, string name, key id, string message)
{
if (channel == MENU_CHANNEL)
{
llListenRemove(listener);
if (message == ">>")
{
Dialog(id, MENU2);
}
else if (message == "<<")
{
Dialog(id, MENU1);
}
else
{
// todo add offsets so box sites perfect on rezzer
llRezAtRoot(message, llGetPos() + <0.0, 0.0, 0.5> , ZERO_VECTOR, llGetRot(), 0);
}
}
}
}

The script itself works fine now, but anytime I try to add something so I can truncate the buttons, I get all flustered trying to figure this out. If you can help, Id be appreciative.
