Hi Hemalatha,
The step 3. is where you receive information from the uploaded file from the popup window. After the user clicks the button "Upload", you need to run the OnNotify action in your screen so that you receive this information and are able to do something with it.
To retrieve this information you have the action Popup_Upload_GetFile, and you need to obtain the Id of the uploaded file using the expression TextToInteger(NotifyGetMessage()). After this, you can access the details of the uploaded file, such as Popup_Upload_GetFile.File.UploadedFile.Filename to obtain the file name.
I have attached a small .oml file that illustrates this.
