Quick Question about Elseif?
I am fairly new to scripting, and wondering, what would the function elseif do? and how would I properly execute it? I know what else does, and can't figure out how to use elseif.

First of all, elseif is not a function. It is a keyword.
The difference between elseif and else is that the former lets you specify a new condition which must be true for the block to be entered, while the latter executes if and only if all previous if and elseifs failed.
It is really just a combination of else and if:
1 | if A then |
2 | -- do something if `A` is true |
3 | elseif B then |
4 | -- do something else if `A` is false but `B` is true |
5 | end |
is equivalent to
1 | if A then |
2 | -- do something if `A` is true |
3 | else |
4 | if B then |
5 | -- do something else if `A` is false but `B` is true |
6 | end |
7 | end |
The former is clearer and should be preferred.

I'd like to add that an `if` statement can have as many `elseif` clauses as you want, but can only have a *single* `else` clause located at the very end. Link150 1355 — 6y
