Please can any one help I am trying to set up an easy worksheet that will record fishing weighs lbs & oz.

I want to list each fishermans weight by name the what they have caught and the an overall weigh column as well.

I can get the formular to add the pound and oz together and to round up the oz to make a whole pound.
example 3lbs 13oz and 2lbs 11oz it comes up with 5.24 instead of 6.05
