Im tring to create a simple aplication that transforms measurements from the us sytem to the metric system. My problem is that the program doesnt seem to recognise comas ( decimal points; eg 17.5 is seen by the program as 175 ) Im using a text box to let the user put in the numbers and a comand buton to perform the equation eg:

Private Sub Command1_Click()
Text1.Text = Text1.Text * 2
End Sub


if you wirgt 1.5 in the texbox

the result will be 30 insted of 3

please help!
