[ruby-core:66203] Excel saveas using a variable

When I run this code in Sketchup, it performs it's duties, then opens
excel, enters the info, then I want it to save as the Address.

And that is where I am having the problem.

Thanks.

 ents=Sketchup.active_model.active_entities
>         prompts = ["Company Name", "Address","One","Two","Three","Four"]
>     defaults = ["My Co","69 Your Street",1.0,2.0,3.0,4.0]
>     input = UI.inputbox prompts, defaults, "Risers"
>         a,b,c,d,e,f=input
> ent = Sketchup.active_model.entities
>  pts = []
>
> pts[0] = [0,c,0]
> pts[1] = [0,d,0]
> pts[2] = [0,0,e]
> pts[3] = [0,0,f]
>
>  # Add the face to the entities in the model
> face = ent.add_face pts
>  face.pushpull 4
> #Open excel and enter info
>   require('win32ole')
>    excel = WIN32OLE.new('Excel.Application')
>    excel.Visible = true
>   workbook = excel.Workbooks.Open('C:\TestFolder\Test.xlsx')
>    ws = workbook.Worksheets(1)
>
> ws.Cells(1,1).Value = a
> ws.Cells(1,2).Value = b
> ws.Cells(1,3).Value = c
> ws.Cells(1,4).Value = d
> ws.Cells(1,5).Value = e
> ws.Cells(1,6).Value = f
>
>   # workbook.SaveAs("C:\TestFolder\" + b + ".xlsx")#trying to get
> 'Customer Address' as the saved workbook
