can't synch my calendar !

Hey guys this seems weird...

When there was no icloud all I had to do was synch my iphone to the computer and I had all my events in calendars that synched = that is what I want

I got icloud thinking it would ease the process... I don't know what I,m doing wrong but it is not working

I have an icloud account

The account on the iphone and computerS include the calendar option to synch my events

The events don't synch even if I do an actualisation when I'm in the calendar on my computer

Even if I plug in my iphone I don't get the events.

Please help anyone have ideas
