GTM irule with geoip

I have been trying to get an irule to work that uses a class match statement with no luck. SO I though I would try finding one here that I know should work:

http://devcentral-sea.f5.com/Tutorials/TechTips/tabid/63/articleType/ArticleView/articleId/1082330/New-Geolocation-Capabilities-in-v101.aspx

whenCLIENT_ACCEPTED {

set region [class match -value [whereis [IP::client_addr] abbrev] equals us_regions]

if { $region ne "" } {

switch $region {

            midwest { pool $region }

            east { HTTP::redirect http://my-east.application.com }

            south { HTTP::redirect http://my-south.application.com }

            west { HTTP::redirection http://my-west.application.com }

    } else { pooldefault }

}

The only difference is that I am using when DNS_REQUESTED.. I keep getting the same error no matter what I do with class match statement. Am I missing something and GTM cant use class match? I am using v 10.2.1.297.0 and this is a 1600 , which F5 sent me to test out the GSLB/geoip capabilities. What am I doing wrong or missing. Also can I verify that my data group is correct.

I have something like this:

class us-regions {

"MA" {"EAST"}

}

error:

line 2: [undefined procedure: class] [class match -value[whereis [IP::client_addr] abbrev] equals us-regions]

thanks for any pointers
