Sure. OK, so you have two functions you might choose between here, and since you opened the post asking for Switch I'm gonna guess you already know that is the one you want to use, so we will just talk about Switch and not If...
The advantage of using Switch over If is that you can write your condition criteria once, then apply it over many evaluation possibilities, instead of having to write If(<condition>, <outcome>) for every single one.
So the Switch function has the following syntax: Switch(<formula>, Match1, Result1, Match2, Result2..., MatchN, ResultN)
You can add as many possible matches and corresponding results as you want (but unlike C# and other language implementations of Switch you have no break operator so you will have to call out one result for one match every time).
So let's try an example. Say we have a text input where a user types in another user's name and we want to control outcomes based on whose name they type in. Say the text field is called "UserName". If they enter CChannon, we then output True. Otherwise, if they enter Ramole, we output False. That Switch statement would look like this:
Switch(UserName.Text, "CChannon", True, "Ramole", False)
We could keep going with this for as many possible conditions as we want to evaluate, so say instead of True/False we want to associate a number with each username, we might write:
Switch(USerName.Text, "CChannon", 1, "Ramole", 2, "UserX", 3, "UserY", 4)
Does that help?
