validation in array

how would i code some kind of validation into this peice of code so it only accepts numbers?? maybe case statements// help

Private Sub Command2_Click()
For this = 1 To 18
num = InputBox("Please enter your scores")
nos(this) = num
If nos(this) < 1 Then
MsgBox "Error please enter a valid number > 0"
this = this - 1
End If
Next this
For Counter = 1 To 18
Text1 = Text1 & " | " & nos(Counter)
Next Counter
End Sub

is there any way to take an array back a loop if the dat entered doesnt meet the required format.:confused:

Could use isnumeric()

what does that mean and who so i set it out i dont understand:eek: :eek: :eek:

try this:

VB Code:

Private Sub Form_Load()
    Dim nos(18) As Integer
    Dim str As String
    Dim i As Integer
    
    For i = 0 To 17
        str = ""
        Do
            Do
                str = InputBox("Please enter your scores")
                If Not IsNumeric(str) Then MsgBox "Must be numerical!"
            Loop Until IsNumeric(str)
            If Val(str) < 1 Then
                MsgBox "Error please enter a valid number > 0"
            End If
        Loop Until Val(str) > 0
        nos(i) = Val(str)
    Next i
    
    For i = 0 To 17
        Text1 = Text1 & " | " & nos(i)
    Next i
End Sub
