Hi,

This one is slightly different to your normal questions of "how do I do this"...This is one is a "what has been done to produce the following..."

Using the following percentages:

Poland Availability: 42.579%
Hungary Availability: 39.370%
Czech Availability: 37.515%
Slovakia Availability: 37.401%

This percentage has been created:

Total Availability: 38.684%

...And I cannot for the life of me work out how...
I think it's through the use of a weighted average, but not exactly sure how you would go about creating that calculation in Excel?

Anyone help??
