Sorry it´me again

But a question. I was starting a project with a Pic16f628a, and want to use an analog input, but when I try to add analog inputI get the message:
"not possible to use this component, the microprossesor need at least one analog input".
When I look at the chip, I see AN0, AN1, AN2, AN3 Am I misunderstanding something. If anybody would try it´s easy, start a new project, select Pic16f628 and try to add an ACD from the inputlist.
Maybe it doesn´t support analog input.
Best regard
Jorgen
