Weldment Cutlist Properties Macro

I have been trying to put weldment cut list properties into my SolidWorks sheet format via a macro.  I was able to find something from another post that mostly works but I am having issues with it.  I am not very experienced in SolidWorks macros so the syntax is new to me.  Below is what I have.  The bolded area is where the program crashes.  It works most of the time, but if I try to have it get properties from a pipe it doesn't work.  Any ideas why?  I think its something to do with the getBodies function but I am not sure what to do about it.

Dim swApp As Object
Sub main()

    Set swSheet = swDraw.GetCurrentSheet

    Set swView = swDraw.GetFirstView

   

    'Find the main referenced view of the document on sheet1.  If default, find the first view.

    If swSheet.CustomPropertyView = "Default" Then

        Do While Not swView Is Nothing

            If (swView.ReferencedDocument Is Nothing) Then

                Set swView = swView.GetNextView 'skip empty sheet "views" etc

                Set swBodyFolder = swFeature.GetSpecificFeature2

               

                'Loop through cutlist looking for body.  Should only be one body, but loop just to be sure.

               For i = 0 To UBound(swBodyFolder.GetBodies)

                    If swBodyFolder.GetBodies(i).Name = sBodyName Then

                   

                        'Body found! This is where the properties are

                        Set swCustPropMgr = swFeature.CustomPropertyManager
