Question Error with code line writing!

[noam309]

Hi,

I use vbnet 2005 pro. and I program for pocket pc wm2003,
I have forms and a modul with my app.
this is a part of the modul:

Public F1 As Double
    Public G1 As Double       ' תוצאות חישוב טופס 5
    Public H1 As Double
    Public I1 As Double
    Public J1 As Double

and this is code is on botton click on a form:

F1 = TextBox4.Text
        G1 = TextBox5.Text
        H1 = TextBox7.Text  '  מצב יניקה
        I1 = TextBox12.Text
        J1 = ""

it means that when I click the botton it send the values in the textboxes into the modul public variables , and I can use these variables on other forms.
the problem is on : J1="" it gives error ,why ?
what should I do when I want to send a zero (nothing) into the public variable in the modul?

hope that I am clear, it gives an error only with this line :J1="" ,should I write this line differently?

thanks.

J1 is declared as Double so you cannot assign an empty string to a Double
Rather try this:

        F1 = TextBox4.Text
        G1 = TextBox5.Text
        H1 = TextBox7.Text  '  מצב יניקה
        I1 = TextBox12.Text
        J1 = 0

Or just ignore it (it's already zero)
