Hello all,

 

My simple programing mind has led me to this implementation of a function. I work at a school, there are three different bell schedules one for Mon&Fri one for Tues&Thurs and one for Wed. I simply want to print on our homepage the time the current Period Ends. Here is what I have, it seems to work, but i am sure there is a way to do this with some while statements maybe even a foreach! Is there anyway someone can show me the error in my ways!

 

Thanks in Advance!

Joe
