I have a homework problem (not looking for answer)asking me to create a program that will calculate the fees for a commercial checking account. It states

A bank charges $10 per month plus the following check fees for a commercial cehcking account:

$.10 each for fewer than 20 checks
$.08 each for 20-39 checks
$.06 each for 40-59 checks
$.04 each for 60 or more checks

Write a program that asks for the number of checks written during the past month, then computes and displays the bank's fees for the month.

Input Validation: Do not accept a negative value for the number of checks written.

I do not want the answer but direction to find out what I am doing wrong. I believe it is not keeping the value for the variable checks

Thanks in advance for any assistance.

remember, = is an asignment operator while == is a condtional check operator.

WoW such a simple issue haha. Thank You very much!!
