      Hi Alex,
      I’m new to javascript so any assistance would be welcomed.

      I have a Form and based on the inputs from several fields I need to set a field to Mandatory (Required). The logic is If any response to “FX” OR “Rates” equals “Derivatives” then set the field “Legal Trading Docs” to Required.
      I seem to be failing on the syntax that sets the field to required.

      I’ve searched the forums and have got as far as:-
      // Onclick
      $(“FX, Rates”).find(“input:checkbox”).bind(“click”,function(){
      customRequiredField();
      });
      function customRequiredField(){
      var a = getFieldValue(“FX”);
      var b = getFieldValue(“Rates”);
      if((a==”Derivatives”)||(b==”Derivatives”)){
      document.getElementById(“Legal Trading Docs”).required = true;
      }else{
      document.getElementById(“Legal Trading Docs”).required = true;
      }
      }
      // On load
      customRequiredField();

      Drew,

      Have you tried using rules to achieve what you want? You can set a field to being required in a rule, so this might work. I have just spent days trying to do something clever in JavaScript only to discover I could have used a series of rules to achieve the same ends.

      Hi,
      Thanks for your reply.
      Yes I’ve been using rules throughout but I need to ensure that when a user goes back and un-checks an enrty that the Required field remains unchanged (at the moment the rules work fine until a user steps back a question – then the rule activates on that question and re-sets the Required fiekd to optional). I just need a function that checks the values of the other question responses to ensure the “Required” state remains if we still have a “Derivatives” selected.

      Hi,
      I’ve been doing a bit more digging on this and the solution proposed here
      Almost covers my situation. All I need guidance on is changing the Yes/No check box (check) to activate based on the value selected from a choice (in my case the choice would be “Derivatives”).

      Any assistance would be very welcome. Thanks in advance.

      Solved:
      using a combination of a couple of solutions posted by Alex on other issues I came up with the following:-

      $(“Field_01”, “Field_02″,”Field_03″,”Field_04″,”Field_05”).find(“input:checkbox”).bind(“click”,function(){
      customSetRequired();
      });

      function customSetRequired(){

      var a = String(getFieldValue(“Field_01”));
      var b = String(getFieldValue(“Field_02”));
      var c = String(getFieldValue(“Field_03”));
      var d = String(getFieldValue(“Field_04”));
      var e = String(getFieldValue(“Field_05”));

      var aa = a.indexOf(“Derivative”);
      var bb = b.indexOf(“Derivative”);
      var cc = c.indexOf(“Derivative”);
      var dd = d.indexOf(“Derivative”);
      var ee = e.indexOf(“Derivative”);

      if(aa>=0||bb>=0||cc>=0||dd>=0||ee>=0){
      spjs.dffs.flag_Mandatory([“Internal_Name_01”]);
      spjs.dffs.flag_Mandatory([“Internal_Name_02”]);
      spjs.dffs.flag_Mandatory([“Internal_Name_04”]);
      spjs.dffs.flag_Mandatory([“Internal_Name_04”]);
      }else{
      spjs.dffs.clear_Mandatory([“Internal_Name_01”]);
      spjs.dffs.clear_Mandatory([“Internal_Name_02”]);
      spjs.dffs.clear_Mandatory([“Internal_Name_03”]);
      spjs.dffs.clear_Mandatory([“Internal_Name_04”]);
      }
      }

      // On load
      customSetRequired();

      Correction (Typo)

      spjs.dffs.flag_Mandatory([“Internal_Name_01″]);
      spjs.dffs.flag_Mandatory([“Internal_Name_02″]);
      spjs.dffs.flag_Mandatory([“Internal_Name_03″]);
      spjs.dffs.flag_Mandatory([“Internal_Name_04″]);
      }else{

      Hi,
      I’m glad you figured it out – I have a hard time following up all emails and forum posts so there will unfortunately be some time delay on my answers.

      Alexander
