Hey guys,

I have an excel file where I have a button to start a new month.
When the button is pressed, it opens an InputBox, where the user has to insert month number.

In vba, I have code to check if the input is a number, anf if that number is between 1 and 12.
When I type a number, everything works as expected. If it's between 1 and 12, it puts the month name in the cell, if it's less than 1 or more than 12, it shows the msgbox.

My problem is when I type letters.
It presents the error "Type mismatch" in "If NumericInput And MyInput >= 1 And MyInput <= 12 Then"

I want the letters to trigger the MsgBox like when the number is not between 1 and 12.

Can anybody help me with this, please?

VBA Code:
Public Sub MyInputBox()

    Dim MyInput As String
    Dim NumericInput As Boolean
    
    'Caixa para input do user quando se carrega no botão
    MyInput = InputBox("Escrever número do novo mês", "Iniciar novo mês", "Número do novo mês")
    NumericInput = IsNumeric(MyInput)
    
    'Pega no que foi inserido e checa se é número e se está entre 1 e 12
    If NumericInput And MyInput >= 1 And MyInput <= 12 Then
        MyInputText = StrConv(MonthName(MyInput, False), vbProperCase)
    
        Call ResetTable
    
        Range("C3").Value = MyInputText
    
    Else
    
        MsgBox "Número de mês mal introduzido"
    
    End If
    
End Sub


Thank you all
