Hi guys,

Got a slight problem with one of my spreadsheets.
I'm populating a spreadsheet with data about our internet speed. The tests are conducted hourly on each day, and to the side of this data I have a summary area where I've set up three cells to display the slowest, fasted and average speed of each day. However, when there is no data in the field I recieve the #Div/0!.
I'm not sure if i can use forumula considering it's already in each cell, and each cell uses conditional formatting also.

Any help is appreciated.
