I have routine that cycles through the Menu on a 4x20LCD (parallax). There is a 'X' that moves up and down so that the user can select an option from the menu. The problem is when the input is triggered the 'X' moves two lines. This happen in up direction and down direction.. Appreciate it if anyone can tell me what i am doing wrong...

You might be to slow with releasing the button. In up and down direction you set menustat to 0, but MonitorInputs is much faster in setting it to 4 or 5 again. So, even if you wait for 0,5 seconds in your if statements the MenuStat will be 4 or 5 again in the next repeat.
Try it with moving the menustat outside of all the if-statements. Put it to the end of the repeat instead and add a repeat which waits for menustat to be <> 0.

  repeat                                                 'Repeat main Program
    
    [color=green]repeat while MenuStat==0[/color]
