You're missing some curly brackets. Try this:

when CLIENT_ACCEPTED {
    if {([TCP::local_port] >= 10514 ) && ([TCP::local_port] <= 10526) || ([TCP::local_port] >= 514 ) && ([TCP::local_port] <= 515) } {
        pool Pool_Name
    } elseif {([UDP::local_port] >= 10514 ) && ([UDP::local_port] <= 10526) || ([UDP::local_port] >= 514 ) && ([UDP::local_port] <= 515) } {
        pool Pool_Name
    } else {
        reject
    }
}
