Combination charts in numbers

Hi everybody!

I want two types of charts in one chart. I want one column chart and one line chart.

The column chart is for the number of sms/month and the line chart is for the price/month.

I can't get it to work in Numbers but I can in Excel.

I've uploaded for you the files so that you can se how I want it.

Excel: http://rapidshare.com/files/98311455/sms_excel.xls.html

Oh, btw the files are in swedish if you wonder 😀

Thanks!
Waldemar
