Hello, everyone.  I am trying to create a workflow rule that looks for the string 'SIA' in the subject of a task.  I set this up as " SIA " so that it would only flag this string, and not include it if it was part of another word (ie., don't flag 'Asia', for instance).  I used 'contains' as the rule criteria.

However, when I run the rule, it is incorrectly flagging tasks that have sia anywhere in the subject line.  If the subject is 'test SIA test', it works like I would expect.  If the subject is 'test ASIA test', though, it is catching and flagging this as well. 

I tried creating a more complex rule that said 'CONTAINS(TEXT(Subject)," SIA "), but when I try to save it I get a strange error about how text expects a number or date, but not a picklist.  I saw that others in the boards had a similar problem with a workflow rule trigger, but couldn't find any other solutions to this.

Does anyone have any thoughts?  Thanks in advance.
