iRule coding

Hi...don't know much about coding in F5 just wanted to verify if this works as a negation (!) as in below.

elseif { [matchregion ldns !"BXB-IDMS-DNS"] } { if { [active_members pl_chi-mysql-read.gtm.intdata.com_3306] > 0 } {....

                                                            Thanks

    I believe you'll need to move the not outside of the braces:

    elseif { not [matchregion ldns "BXB-IDMS-DNS"] } { 
 if { [active_members pl_chi-mysql-read.gtm.intdata.com_3306] > 0 } {....

      Either one will work. Sometimes it's easier to understand upon glancing at it when you spell it out instead of using symbols. End result is the same though.
