How to give the player achievement after acquiring two specific achievements?

I’m gonna keep this simple.

We have achievements based on “scanning” things.
The problem is (in my opinion), it works only if you have to do something once.

And I would like to track, if the player has two determined achievements and then, give him third.

I’ve followed this: https://answers.unrealengine.com/questions/323899/bug-steam-achievement-progress-instant-unlock.html
Did the same and now I’m totally lost.

Could anyone help?

I thought about something like “if a player has achiev_one and if a player has achiev_two then give him achiev_third”. But I have no idea how to make this happen :frowning:

Oh, and one more thing. Unfortunately, I am not a programmer so, please. Don’t hit me with a very complex language :smiley:
