Can someone tell me why I can not assign the same ("c") to my lblPart as I did my other labels? and also advise how to get the sum of all labels. Thanks.

Public Sub btnCalculate_Click(sender As Object, e As EventArgs) Handles btnCalculate.Click

Dim Sum1 As Double

Dim Result As Double

'Dim lblLabor As Double '<<< rename lblLabor

Dim CalcMiscChages As Double

Dim SumMisc As Double

Dim dblBoxLabor As Double

Dim dblBoxParts As Double

Dim dbllblLabor As Double

Dim dbllblParts As Double

Dim dbllblTax As Double

Dim decTotalCharges As Double

Dim decTax As Double

```
If ValidateInputFields() Then
Result = CalcOilLubeCharges(dblOilChange, dblLubeJob) + CalcMiscCharges(dblInspection, dblReplaceMuffler, dblTireRotation) + CalcFlushes(dblRadiatorFlush, dblTransmissionFlush)
lblLabor.Text = (txtBoxLabor.Text + Result).ToString("C")
lblParts.Text = dectxtBoxLabor
lblTax.Text = (txtBoxParts.Text * decTAX_RATE).ToString("c")
```
