What This VBA Code Does
This VBA code will show how to keep cycling through an input box prompt until the user gives you a valid response. My example below asks the user for his/her age and will continue to make the input box reappear in the event the user tries to be cute and enter an outrage age (such as "-20" or "200"). You will also need to make sure you capture if your user hits the Cancel button or else they may be looping forever!
Let me know in the comments section below how you plan to use this snippet to make sure your VBA code gets the proper inputs every time!
'PURPOSE: An example of how to keep looping an input box until a valid answer is entered
Dim InputQuestion As String
Dim myAnswer As Variant
'Question to pose to the user
InputQuestion = "Please enter your age." & vbNewLine _
& "(Don't even think about lying!)"
'Keeping looping until you get a valid answer to your question
'Retrieve an answer from the user
myAnswer = Application.InputBox(InputQuestion, "Your Age?", Type:=1)
'Check if user selected cancel button
If TypeName(myAnswer) = "Boolean" Then Exit Sub
Loop While myAnswer <= 0 Or myAnswer > 120
'We've got a valid answer from the user, let's continue on...
