How to create a variable door?

I would like to create a door so that if a player has a certain amount of a variable (cash) it will let them pass, otherwise stop them coming through. I need help with a script I can use to put this into a brick.

Thanks,

1. Learn about the touched event and learn how to use it
2. Learn how to check if a player is touching
