Help Help With Extractableitems

[ton3]

Hi guys, I'm trying to make a Gift box who give newbies some items but I'm facing a problem.

 

 

- It doesn't let me add more than 1 item with chance 100%

- I can only add items like this: Item 1 with 50% and Item 2 with 50% = 100%

- If I try to add 2 items like this: Item 1 with 100% and item 2 with 100% chance it doesn't work.

You can't do anything like that with regular autoextractable for the simple reason there is no such needs on vanilla. Meaning you have to implement it by yourself.
