This script is working but I want to have a random rate of ITEM A to be exchanged to ITEM B. Numbers are 1, 2 or 3 maximum. So for example, the script returned 1 as the exchange rate, it would be like this: 1 ITEM A = 1 ITEM B. Then another session if the script returned 3 as the exchange rate, then 3 ITEM A = 1 ITEM B. The npc must show the random rate after the player has got the exchanged item.

 

I can pay to have something like this.

EXAMPLE: When the npc is clicked, it will ask how many ITEM A the player wants to exchange. So for example, if the player has 20 pcs ITEM A, and he puts all 20 to exchange and the script gave him 3 as the exchange rate, he will only receive 6 ITEM B and only 18 ITEM A will be decreased in his inventory. Meaning, 2 ITEM A will be left. 

 

Alternatively, if the player puts 20 to exchange and the script gave him 1 as the exchange rate, then he will receive 20 ITEM B all in all with no ITEM A left in his inventory.
