So what if you created an account detail page with an account model that has two conditions that are equal to URL parameters usercode and subuser. Then you could create a page that has two UI only fields of UserCode and SubUser and a button. The user would enter their code and sub user in the UI only fields then the button would redirect them to the URL of your account detail page that would include “&usercode={{$Model.YOURMODEL.data.0.UserCode}}&subuser={{Model.YOURMODEL.data.0.SubUser}}” at the end of the URL. The account detail page will only load records that match those URL parameter. If no records match those parameters, then no records would display. You could then have a template or rich text that is set to conditionally render if no records are in your account model. This would display your error message if no records match the UserCode/SubUser combo. You could also do this using a page include and display it inline or in a popup.

This little example will (simplified to fit on one skuid page) show how it can be done:
