Here is my code.Please let me know where i was going wrong?

TabController controller = new TabController();

newTab = new TabInfo();

newTab.PortalID = PortalId;

newTab.TabName = "OfficeMap";

newTab.Title = "OfficeMap";

newTab.Description = "OfficeMap";

newTab.KeyWords = "Office";

newTab.IsDeleted = false;

newTab.IsSuperTab = false;

newTab.IsVisible = true;

newTab.DisableLink = false;

newTab.IconFile = "";

newTab.Url = "";

newTab.TabPermissions = PermGrid.Permissions;

controller.AddTab(newTab);

DataCache.ClearModuleCache(newTab.TabID);

Response.Redirect(Globals.NavigateURL(TabId));

ModuleController modCtr = new ModuleController();

ModuleInfo modInfo = new ModuleInfo();

modInfo = modCtr.GetModuleByDefinition(PortalSettings.PortalId, "OfficeMap");

newTab = controller.GetTabByName("OfficeMap", this.PortalId);

modInfo.TabID = newTab.TabID; modInfo.ModuleTitle = "OfficeMap";

modInfo.PaneName = "ContentPane"; modCtr.AddModule(modInfo);

Well for one - as soon as the code hits this line -

Response.Redirect(Globals.NavigateURL(TabId));

It will redirect
