Irule to External Data Group not pulling up second data field

Here is the final version of the iRule

when RULE_INIT {
  Turn Debug on or off (0=off 1=on)
  Turn debug off in prod
  set static::redir_debug 1
}
when HTTP_REQUEST {
  Use following to match against datagroup

  Lookup the redirect or pool based upon match_string value
  set goto [class match -value [string tolower [HTTP::host][HTTP::path]] starts_with www_ou_edu_redir_class]
  if {$static::redir_debug}{log local0. "Goto: $goto"}
  if { [getfield $goto "," 1] equals "pool" }{
    if {$static::redir_debug}{log local0. "Pool declaration detected. Going to: [getfield $goto "," 2]"}
    pool [getfield $goto "," 2]
  } else {
    if {$static::redir_debug}{log local0. "Redirect declaration detected. Redirecting to: [getfield $goto "," 2]"}
    HTTP::redirect http://[getfield $goto "," 2]
  }
}

and then here is a sample of the external Datagroup file that goes with the rule that works.

ags.ou.edu := "redir,www.ou.edu/ags.html",
ags.ou.edu/~ := "redir,parker.ou.edu",
airport.ou.edu := "redir,www.ou.edu/airport.html",
alc.ou.edu := "pool,ouwww_bostitch",

so what i was missing, which was pointed out here was the fact that the F5 was unable to pull out the second part of the data. encapsulating the data in Double Quotes enabled that to work.
