          - Specify 110 in the Width field. 
 
          - Create a text box that lines up with the label you created in Step 2.

          - Change the name of the text box. 
           
            Ensure the label name does not contain spaces and does not exceed 32 alphanumeric characters.
           
 
          - Copy the default text from the Hidden_Messages label to the text box.

          - Update the alert message manually with the new ID.
