I can't seem to get part of this trigger to work.

The bolded parts of this trigger don't work. It doesn't create nor remove the item I want it to.

The shop has the Sell Items ability I assume.

 

[Champ-Bear]

Yes, and I can actually get the first upgrade to work, and it adds the second icon for the second upgrade, but it doesn't remove the first icon.

I never knew you can remove items from selling? Or is that an ability?

Anyway, possibly, the store is not 040 <gen> but something else..

You could change that to Triggering Unit and maybe it will fix it

 

[Champ-Bear]

Well removing it is a trigger, but I can't seem to get it to work. And that is the correct store. Changing to triggering unit doesn't fix it, nor does changing it to the seller of last sold item.

 

[Azylaminaz]

You could replace the shop with a different shop that has different items to be sold.

Removing items only works on items that have also been added by trigger.

So, ermm, what would the trigger look like? I still can't get it to work. And although I can get it to add the second item with my trigger (but not remove the first one), when I purchase it, it just falls to the ground, and the trigger then doesn't work even if I pick it up from there.

You should have some kind of initialization trigger, where you add those items to the shop.
