I am a novice to Dnn. I want to install the Store module with both Dnn install version and Store install version to farmiliar with DNN GUI and operations.  I just follow the Wrox "Professional...." book to do that. After install the module. I found that the Store menu modul include 3 controls. CategoryMenu.ascx, CatalogEdit.ascx, CategorySettings.ascx. I just worry if the CatalogEdit.ascx has been put in a wrong place.  Should the Store menu module contain the CategoryEdit.ascx control?  I found that the CatalogEdit.ascx control to be included in the Store Catalog module already?

After I install the Store menu module into the left pane,  I config the module within this module settings, to enable this module to be viewed by all user, and display module on all pages. and then I input the product categories. But the child portal displayed that this module is "An error has occurred. Store settings are not defined." In Main portal displayed that this module is "Store settings are not defined. DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Store.WebControls.CategoryMenu.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---"

I don't know how to do the further to the module settings. Pleas help me. Thanks.
