Error Evaluating Filter

I have been reading the forums and the User Guide but still unable to get a simple filter to work.



I only want to accept ADT^A08 or ADT^A31 messages and filter out any other ADT's. Using the Rule Builder I originally tried 'Accept message if MSH9.2 = A08 or A31. When this didn't work I tried again just using A08 (and then A31) same problem, error thrown for any message.



In one attempt I accidently had accept message if MSH9.2 = blank,,,,and this worked/no error, it filtered an A31.....



I also tried unchecking 'strip namespaces' from my inbound Message Template properties based on something I read in another forum post. Didn't help.



The filter is in source filter for a channel that is reading from file inserting to db although I may want to use the same filter in an LLP to File channel.



hoping I can get an answer on how to build a simple filter on a source to filter out certain message triggers using rule builder.



thanks
