how do select item inventory puzzle work?

I am very confused on how the "Select Item" event works, they way I want it to work is that you select the wanted item and it raises the variable and for any other item it does not, but it still raises the variable even if it is any other item. if it helps, I have the ID of the item as it's listed variable (example item id/variable = 0001) so perhaps I am getting this whole ID thing wrong. am I just being stupid? I would really appreciate some help.

Basically the 'select item' function outputs the ID of the selected item into your chosen variable.

what

Lemme explain it better.
When you use the 'select item' command you have the option to choose any variable you want, you also choose a category of items from which the player will pick from. Then, in-game the player is given the choice to pick an item from the category you picked. They select an item. And then the ID of that item is stored in the variable.

For example if the player picked item # 3 the variable which you choose will change to 3.

can you please explain a bit more in depth? i don't think i completely understand and i also don't know what defines the item's ID.

oh okay

Here is a screenshot showing where you can find the item ID

so say if I, have the variable as Chumblo let's say for hypothetical cases, if I selected Item #11, it's variable would go up by 11?

Yes, exactly!

oh okay! I think I get it know. All I have to do to get this stuff working is to have the "IF VARIABLE IS BLANK NUMBER" set to what ever the ID of the item to get it going how I want! Ureka I have the KEY mechanic of my game figured out!... I think I do at least.

so wait if I use the item does it add to the variable or just instantly set it to the Item's ID?

It sets it to the item's ID.

okay that's good to know. both for me and anyone in the future who has the same woe as me. Don't want to have to reset the variable to do the puzzle.
