[RESOLVED] Need help setting up an event.

[Sigma]

It's a simple puzzle in theory of inputting a three number code into a computer which will unlock a door.
How do I go about doing this? I'm sure variables are involved somewhere.

[modern algebra]

There is an event command called Input Number on the first page I think about 5 commands down in the first column. Do that, allow for three digits, store it to a variable, then use a fork condition to test that the value in the variable = the code.
