Property Sheet/Page in Wizard Mode

Hello,

I'm a newbie to the post so i'm not sure if i've posted correctly but here's my problem:

I've set up a property sheet app with several property pages in wizard mode. When I set up edit boxes with range control values, and I test the range notification by deliberately placing an invalid number in the edit box and clicking my property sheet "next" button, I get two error notification dialog boxes.

I suspect it has something to do with the property sheet and the property page both sending this notification. I looked in some of the documentation I have to try and catch one of these errors but I could find nothing. I think I need to catch one of the dialog notifications, but I'm not sure being somewhat new to MFC programming.

Thanks in advance,
Joe
