Limitations of Select Case
Now, you may be thinking, "if Select Case is so efficient, why use

Select Case statement only allows you to check if a variable is equal to a value - you can't test to see if it is greater than, less than etc. Also, you can only test against one variable. If you have multiple variables to test against, you'll need to use an
