The topics in right navigation of customer portal knowledge base do not match the order I've sorted them in agent portal.

The topics in right navigation of customer portal knowledge base do not match the order I've sorted them in agent portal.

From the agent portal I structured my topic folders for the knowledge base in a A, B, C, D, E order.  When I view it from my customer portal it's all scrambled?  Why do they not show in the customer portal in the same order that I have them arranged in my agent view?  This is an urgent question.  Please respond promptly.  

Thank you!
