Hi. The code below works. The problem that I have is that there are some parts that have a space in the Revision_ID field. If there is a space I would like it to put REV. - in the field. How can I use a case to filter these?
              WHEN NULL THEN ' REV. -'
	      ELSE ' REV. ' + REVISION_ID

Like this?

               WHEN NULL THEN ' REV. -'
              WHEN ' ' THEN ' REV. -'
              ELSE ' REV. ' + REVISION_ID

' REV. ' + CASE when REVISION_ID is null then '-'
                     when ltrim(revision_id) = '' then '-'
                     else ltrim(str(revision_id))

if revision_id is a NOT an int or other number field, change this:
else ltrim(str(revision_id))

else revision_id

Thanks it is now working when there is a space. I still need to refine it because if Revision_ID is null then the result is Null also. Any ideas?

I believe you tried my solution, which won't quite work as WHEN NULL doesn't quite work as expected..

Try Brandon's solution (24110103) which should work..
