Adjust Microsoft Word table width via LotusScript

Here is the script:

 Set wrdApp = CreateObject
("Word.Application")
 wrdApp.documents.add
(xtempDrive$+"mydoc.doc") 
 
 wrdApp.Visible = True
 
 ' Add a new document
 
 Set wrddoc = 
wrdapp.Application.ActiveDocument
 
 Set wrdSelection = wrdApp.Selection
  Set range = wrdSelection.range
 Set tables = wrdApp.Selection.tables.add
(range, 1,7)
 
 Dim wdAdjustProportional As Integer
 Dim wdAdjustNone As Integer
 Dim wdAdjustFirstColumn As Integer
  
 wdAdjustProportional = 1
 wdAdjustNone = 0
 wdAdjustFirstColumn = 2
 
 wrdDoc.Tables(1).Columns(1).
SetWidth 1.18, wdAdjustProportional
 wrdDoc.Tables(1).Columns(2).
SetWidth 0.02, wdAdjustProportional
 wrdDoc.Tables(1).Columns(3).
SetWidth 2.5, wdAdjustProportional
 wrdDoc.Tables(1).Columns(4).
SetWidth  "0,02", wdAdjustProportional
 wrdDoc.Tables(1).Columns(5).
SetWidth "1,3", wdAdjustProportional
 wrdDoc.Tables(1).Columns(6).
SetWidth "0,02", wdAdjustProportional
 wrdDoc.Tables(1).Columns(7).
SetWidth "1,12", wdAdjustProportional
 wrdDoc.Tables(1).Rows.Alignment 1
' wrdDoc.Tables(1).Rows.SetLeftIndent -21.6 
 

But LotusScript gives me this error, "Value out of range" when it hits the first "wrdDoc.Tables(x).Columns(x).SetWidth "xxxx", wdAdjustProportional."
