Table in word VBA

HiI've a problem when I'm going insert a table in word VBA.I want to insert a table in word VBA, a object table.My code:Dim tabela as tableset tabela = ActiveDocument.Range(0,0)ActiveDocument.Tables.Add range:=tabela, numrows:=3, numcolumns:=3When I compile this simple code, the following message come:"Value out of Interval!"Of the other manner that is insert the table on a selected point of the document like thisset tabela = Selection.RangeSelection.Tables.Add Range:= tabe, numrows:=3, numcolumns:=3On this, the error message is:"Incorrect Type!"I think that the two manners are right, but as the first as the second are wrong.Why this thing occurs?
