Quick Question

Im working on a project that i soon hope to release to all of you at Sythe I just need one question to be answered

Code:

 Dim a As Double = TextBox1.Text
        Dim b As Integer = 4
        If TextBox2.Text = "2" Then Dim d As Integer = 213

I need to know if i can Dim d as more than one thing ive done this already but it says name "d" is not declared even though i declared SO MANY times before.
Help would be appreciated!
P.S. As soon as im done i will gladly give a tut on one of the things in the project for everybody

 

second one is correct.

 

Ok thanks alot
