[2008] simple question with my if statement.

[Jmack]

hey

I have made an if statement for when i error check for fields which are supposed to have numbers in it. Atm, my statement says that if either of the text boxes are blank display error and if they have 2 numbers work out the answer. I was wondering how i can get the code to display an error message (msgbox) when both the fields are text. I know for numbers it is "isnumeric" but i cant figure out how to say if it is text.

when one of the text boxes is a letter, it displays error because the other one is blank, but if the first one has a letter and the second one has any character it doesnt display the error

I only need that little bit and i should be able to put it in >.< its been plaguing me haha

thanks in advance
josh

Private Sub btnCalculate1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate1.Click
Message = txtNumber1.Text + "+" + txtNumber2.Text
number1 = Val(txtNumber1.Text)
number2 = Val(txtNumber2.Text)
If IsNumeric(txtNumber1.Text) And IsNumeric(txtNumber2.Text) Then
txtAnswer1.Text = Message + " = " + Str(number1 + number2)
ElseIf (txtNumber1.Text = "" Or txtNumber2.Text = "") Then
MsgBox("Please enter a valid number")

End If
End Sub
