calculating multiple payment types

Sorry guys but still not working quite the way it's meant to.

I forgot to mention that you can either work a day or night or double. When hours are input for AM and PM or PM only it works perfectly but if you only work an AM the results get messed up.

Anymore help would be greatly appreciated. I've tried to work with it but can't get it quite right. USing the example attached in previous post as it's exactly the layout I need.


Thanks again
