I'm trying to calculate values what are in textboxes, but i got some error.
Error : Input string was not in a correct format.
TextBox4 = answer
TextBox8 value is = 400
TextBox12 value is = 0,000555555555555555
TextBox4.Text = Val(TextBox8.Text) * Double.Parse(TextBox12.Text)
Anyone know what's the problem ? and how to fix it or other way to make it ?
EDIT: I fixed it myself
