VB not showing error message in Else clause

I am trying to make a program that displays an error message in a StatusStrip control whenever the user doesn't enter a numeric value or a numeric value that falls within a certain range and gives the TextBox with aforementioned incorrect information focus after the user clicks the "Calculate" button. It displays the error message when the user fails to enter a numeric value in a TextBox but when the user enters a number outside the specified range it only gives focus to the TextBox and doesn't display the error message in the StatusStrip control. Please help.

    Dim dblFiveWeekSum As Double    ' Sum of temperatures for five weeks
