iRule syntax error

Hello

Could you please help me correcting my following iRule?

I am newbie to iRules, so I couldn't figure out the error.

when HTTP_REQUEST {
  switch -exact -- [HTTP::uri] contains "/info/capacity" {
    if {[active_members pool_test1 ] >0 } {
      pool pool_test1 
    } else {
      pool pool_sorry
    }
 } "/execution/v1" {
    if {[active_members pool_test2 ] >0 } {
      pool pool_test2
    }   
  }  else {
    pool pool_sorry2
  }
}

ERROR

01070151:3: Rule [/Common/test_iRules] error: /Common/test_iRules:2: error: [undefined procedure: /info/capacity][/info/capacity]
/Common/test_iRules:8: error: [undefined procedure: /execution/v1][/execution/v1]
/Common/test_iRules:12: error: [undefined procedure: else][else]

I try to do this 

contain "/info/capacity" & active_members pool_test1 >0 → pool_test1 

contain "/info/capacity" & active_members pool_test1 <0 → pool_sorry

contain "/execution/v1" & active_members pool_test2 >0 → pool_test2

contain "/execution/v1" & active_members pool_test2 <0 → pool_sorry2

Thanks

    You're syntax is slightly off, try this

    when HTTP_REQUEST {
    switch [HTTP::uri] {
        "/info/capacity" {
            if {[active_members pool_test1 ] >0 } {
                pool pool_test1 
            } else {
                pool pool_sorry
            }
        }
        "/execution/v1" {
            if {[active_members pool_test2 ] >0 } {
                pool pool_test2
            } else {
                pool pool_sorry2
            } 
        }
    }
}
