I am need of help asap, I dont understand exactly where I am going wrong but now I may of flustered myself and can't see for looking.

I am building a downtime report from multiple sheets in 1 work book.
as i have several different codes for downtime each daily production sheets has the calcs at the bottom and i am trying to get my downtime sheet to look it up and give a figure for each code on each day.
i have attached the wookbook so you guys can see what i mean.
you will see i have tried a few different things in the report sheet but nothing seems to work correctly.
if anybody is able to help, would you be able to show or explain where i am going wrong so i can learn from it.
