Alter Index issue & Try/Catch question

All,
I'm currently modifying a BOL procedure to rebuild/reorganize my
indexes. I've changed the ALTER INDEX command so that it performs the
rebuild online. The first time I ran the script, it errored with the
following error below:
Msg 2725, Level 16, State 2, Line 1
Online index operation cannot be performed for index
'Company$Attachment$0' because the index contains column 'Entry Pointer
ID' of data type text, ntext, image, varchar(max), nvarchar(max),
varbinary(max) or xml. For non-clustered index the column could be an
include column of the index, for clustered index it could be any column
of the table. In case of drop_existing the column could be part of new
or old index. The operation must be performed offline.
At this point, I have tried to integrate the TRY/CATCH routine so that
when this error appears, the script executes the ALTER INDEXES offline
instead (script below). I was wondering if there is a way to possible
write out the error to a log file perhaps?
Thanks,
Ian
