Below is my AfterUpdate code for TextBox12. Part of that code gives me a
message if an incorrect time is entered (like 2845 instead of 1845). Is
there any code that I can place after the MsgBox so that the number in
TextBox12 will be selected. My goal is to prevent them from moving on until
the correct number is entered.

TimeValue(TextBox11.Value)) * 24
