I can't figure out how to use the validation "Contains" field. I want users to be able to enter numbers and letters only (No space or special characters), but I'm not sure what language/code should I enter here for that purpose.

You need regex, not "contains".
/^[A-Za-z0-9]*$/
/^[A-Za-z0-9]*$/

However, for my knowledge, what is the use for "contain" and how do you use it?
