Saving in lists

I am having a problem using a web part that saves data to a custom list. Everytime I try to save and close from the site it gives me the error "This form cannot be saved when previewing this page." This is a simples web part and simple list i have no idea what the problem is, can anyone help me?

Here is the code for the web part:

<WebPartPages:ListFormWebPart webpart="true" runat="server" __webpartid="{30EA3BDD-5EBB-4E2A-9B31-C15C167ACF59}">
