Scratch

1. so i'm making a vending machine game where every treat is assigned a number, like 105 or 110, and all those numbers are added to a list. then i have a keypad where you input a 3-digit number. each number is stored in a variable. then i have a done button that, when clicked, combines the numbers from those variables and puts them in another variable, called entry. it is then supposed to check if the list contains "entry" and do process 1. if it does not, it is supposed to do process 2. every time it does process 2, even if the number is in the list.

2. i have a ground and a cliff, both the same color. they are part of the background. i have a sprite that is supposed to not move if touching that color, but now it wont work because it is touching the ground.

hope someone can help.
thanks
