I have problem in VB

Im trying to create a program that will convert English to Metric System but it comes with error and can not display the result in RichTextBox.

Dim miles As Double

Dim yards As Double

Dim feet As Double

Dim inches As Double

Dim meters As Double

Dim kilometers As Double

Dim centimeters As Double

Dim totalInches As Doublemiles = CInt(txtMiles.Text)

yards = CInt(txtYards.Text)

feet = CInt(txtFeet.Text)

inches = CInt(txtInches.Text)

totalInches = 63360 * miles + 36 * yards + 12 * feet + inches

meters = (totalInches / 39.37)

kilometers = Int(meters / 1000)

centimeters = (meters / 100)kilometers = (totalInches / 39.37) / 1000

meters = (kilometers - Math.Floor(kilometers)) * 1000

centimeters = (meters - Math.Floor(meters)) * 100With DialogResult.

.Clear()

.Add("The metric length is:")

.Add(Math.Floor(kilometers) & " kilometers")

.Add(Math.Floor(meters) & " meters")

.Add(Math.Round(centimeters, 2) & " centimeters")

End WithWith lstDialogueResultsItems.

.Clear()

.Add("The metric length is:")

.Add(kilometers & " kilometers")

.Add(meters & " meters")

.Add(centimeters & " centimeters")

End WithEnd Sub

but it comes with error and can not display the result in RichTextBox.

And? What's the error? Where's the error?Is it in the With lines? Because you should remove the trailing period off those lines.
