Found unicode characters in the script, otherwise was fine.

Added FILLFACTOR to the script - important!

1. added declaration at the top:

declare @fillfactor int

2.Added the assignation just above the comment shown here:

select @fillfactor = isnull(fill_factor,90) from sys.indexes where object_id = @idxid

-- Get the number of cols in the index

3. Then modified the beginning of the "build the options" section:

-- Build the options

set @sParamSQL = ' WITH (FILLFACTOR = ' + cast(isnull(@fillfactor,90) as varchar(3)) + ', '
