[SOLVED] Win32API Wizard97 PropSheet_SetWizButtons not working

I'm just learning the Win32 API using C, and I needed to add wizard to my application. This is the first time I've ever done this, so I'm sure there's multiple things wrong with this code.

I've been studying the MSDN website, and I've based this implementation on my interpretation of the examples and explanations offered there. What am I missing here? The wizard buttons aren't changing, and clicking Next on the last page of the wizard does nothing.

The only way to close the wizard is to press the cancel button. I'm lost. Any help is greatly appreciated!
