I am trying to write an extremely basic Macro and it is giving me fits. I just want a user form that will allow the user to input the length and diameter of a cylinder and SolidWorks draw and extrude it for them. I literally watched a step by step tutorial and almost copied the code word for word but it is giving me the error "Compile Error: Sub or Function Not Defined". I have absolutely no idea why it isn't working but this is my first time writing a macro code for SolidWorks so it could be something blatantly obvious that I am missing. Any help would be greatly appreciated.

Here is my code:

' ******************************************************************************

' C:\Users\awallace\AppData\Local\Temp\swx1764\Macro1.swb - macro recorded on 11/28/16 by awallace

' ******************************************************************************

Dim swApp As Object

Dim Part As ModelDoc2

Dim boolstatus As Boolean

Dim longstatus As Long, longwarnings As Long

Sub main()

     'Display User Form

     UserForm1.Show

     'Opens new part in SolidWorks

     Set swApp = Application.SldWorks

     Set Part = swApp.NewDocument("C:\ProgramData\SolidWorks\SOLIDWORKS 2015\templates\Part.prtdot", 0, 0, 0)

     swApp.ActivateDoc2 "Part2", False, longstatus

     Set Part = swApp.ActiveDoc

     Dim myModelView As Object

     Set myModelView = Part.ActiveView

     myModelView.FrameState = swWindowState_e.swWindowMaximized

     boolstatus = Part.Extension.SelectByID2("Front Plane", "PLANE", 0, 0, 0, False, 0, Nothing, 0)

     Part.SketchManager.InsertSketch True

End Sub

Public Sub CreateCylinder(InputLength As Double, InputDia As Double)

    'Define Variables

    Dim CylinderLength As Double

    Dim CylinderDia As Double

    'Inputs User Values

    CylinderLength = InputLength

    CylinderDia = InputDia

    'Convert to Meters

    CylinderLength = ConvertToMeters(CylinderLength)

    CylinderDia = ConvertToMeters(CylinderDia)

    'Creating the SketchManager

    Dim swSketchManager As SketchManager

    Set swSketchManager = Part.SketchManager

    'Create Circle

    Dim TheCircle As SketchSegment

    Set TheCircle = swSketchManager.CreateCircle(0, 0, 0, CylinderDia / 2, 0, 0)

    'Creating the SketchManager

    Dim swFeatureManager As FeatureManager

    Set swFeatureManager = Part.FeatureManager

    'Create Circle

    Dim TheLength As Feature

    Set TheLength = swFeatureManager.FeatureExtrusion2(True, False, False, swEndCondBlind, swEndCondBlind, CylinderLength, 0, False, False, False, False, 0, 0, False, False, False, False, False, False, False, False, False, False)

End Sub

Here is also the code for the userform:

Private Sub CommandButton1_Click()

    'Create Variables

    Dim Length As Double

    Dim Dia As Double

    'Set User Inputs Equal to Variables

    Length = LengthTextBox.Text

    Dia = DiaTextBox.Text

    Call CreateCylinder(Length, Dia)

    End

End Sub
