Forum:Trouble with appearance genes

I'm having some troubles with a custom genome that I'm making for C3/DS. The problem is that I want the appearance to change as the norn grows(goes through the various life stages). But no matter what I do, the genes won't switch on(for example, the body won't change when the norn ages to child, it still has it's original baby body).

So what can the problem be here? Any help is appreciated! The tool used is the official GW Genetics Kit.
