Hi does anyone know how to display a value in a parameter?

I'm trying to store a value from a form textbox into a mySQL database.

However it seems that i'm getting an error saying i'm passing a null value even after i typed something into the textbox, so i'd like to see what is being passed. this is the code:

Dim CustNameParam as New odbcParameter("@CustName", odbcType.Varchar, 50)
CustNameParam.Value = txtName.text
cmd.Parameters.Add(CustNameParam)

i'd like to see what is in the CustNameParam.

Any help?

Thanx!

Maybe the problem has occured at this line:
CustNameParam.Value = txtName.text;
Changed the line to
CusNameParam.Value=Convert.ToChar(txtName.text);
