Formula required to calculate points for football results prediction

Hi there

I'm creating an (English) football predictions competition for me and my family.

One problem that has stumped me is how to get the scores based on the 'home' & 'away' score predictions.

The rules are: If I predict the correct exact result I get 3 points. I want to add another 'rule' whereby if I predict the correct winner, I get 1 point. Incorrect predictions get 0 points. I don't know how to do this using a formula.

Please can someone tell me what I need to write? The online Microsoft Excel 2007 help only confused me further! Please see the example spreadsheet attached; I've added examples and explanations of what the scores should be...

I can offer PowerPoint assistance in return; Excel is not my area of expertise!

Many thanks
Jenny
