I want to make a sunburst chart

[Morty07]

Hi!
I want to make sunburst chart for my company showing, an annual cycle.

The cycle will show month, week, day and what action to take.

I have made an excel sheet wich contains my data, see enclosed picture.
[TABLE="width: 500"]
<tbody>[TR]
[TD]Month[/TD]
[TD]Week[/TD]
[TD]Weekday[/TD]
[TD]Activity[/TD]

[TD]Januar[/TD]
[TD]Uke 1[/TD]
[TD]Man[/TD]
[TD]Vareopptelling[/TD]

And so on.
What happens is that I does not show anything. Phuuu

Can anyone take a look on it and perhaps tell me what I am doing wrong.

Sincerely
