SNAT using specific IP based on the client IP range

I'm needing to use an iRule to determine if a client connection comes from IP 10.1.0.0/25 then SNAT using a specific IP instead of the default AutoMap SNAT IP. I found the iRule below and have tried...
application delivery
iRules
LTM

 when CLIENT_ACCEPTED {      
   if { [IP::addr [IP::client_addr] equals 10.1.0.0/25]} {        
     snat 10.1.5.5          
   }       
 }

    You were close just missing a close brace at the end of the if condition.

    Thank you Kevin for tidying up. I'm going to accept James Lee's answer since it initially led me in the correct direction. Below is what I ended up with that does what I need. Thank you both!

     

    when CLIENT_ACCEPTED {

     

    if { [IP::addr [IP::client_addr] equals 10.1.0.0/25]} {

     

    snat 10.1.5.5

     

    }

     

    else { snat 10.1.5.6 } }
