redirect incoming specific IP address to one of the node in the pool

Hi,

Can anyone let me know how to redirect specific client incoming IP address eg. 208.97.21.100 to specific node eg 172.16.5.10 in the pool? I have following iRule

when CLIENT_ACCEPTED {
   if { [IP::client_addr] equals 209.152.196.190] } {
       pool Member-Portal member 172.16.5.35 80
   }
}

I'm getting below error when applied this iRule to my virtual server.
