Hello,

I am displaying questions on a VF page and their options in form of radio buttons, but when I try to get the selected values of all the radio buttons and insert them for each record, blank value is passed.
Following is my code :
VF PAGE :
<apex:page controller="DisplayController" sidebar="false">
  <apex:form >
        <apex:repeat value="{!Questions}" var="q">
          <apex:outputField value="{!q.Related_Question__r.Question__c}"/>
          <apex:selectRadio value="{!q.Related_Question__r.Selected_Value__c}" id="RadioButtonValue" >
             <apex:selectOptions value="{!Options}" ></apex:selectOptions>
          </apex:selectRadio><br /><br />
       </apex:repeat>  
     <apex:commandButton action="{!SubmitSurvey}" value="Save" title="Save"/>
  </apex:form>
 </apex:page>


APEX CONTROLLER :
public with sharing class DisplayController {

    Public Survey_Main__c mainobj{get;set;}
    Public Survey_Question_Table__c questobj{get;set;}
    Public Survey_Option_table__c optobje{get;set;}
    Public List<Survey_Main__c> mainList{get;set;}
    Public List<Survey_Question_Table__c> questList{get;set;}
    Public List<Survey_Option_Table__c> optList{get;set;}

    Public String SelectedValue{get;set;}

    Public DisplayController(){
        
    }

   Public List<Survey_Option_Table__c> getQuestions(){
    
        optList = [select id, name,Option_One__c,Option_Two__c,Option_Three__c,Option_Four__c,Option_Five__c,Answer__c, Related_Question__r.Question__c,Related_Question__r.Selected_Value__c,Related_Question__r.Related_Survey__c from Survey_Option_Table__c where Related_Question__r.Related_Survey__c = 'a0d28000001GVcw'];
        
        return optList;
    }


    Public List<SelectOption> getOptions(){
        questList = [select id, name, Question__c,Selected_Value__c,Related_Survey__c from Survey_Question_Table__c where Related_Survey__c = 'a0d28000001GVcw'];
        optList=[select id, name, Option_One__c,Option_Two__c,Option_Three__c,Option_Four__c,Option_Five__c,Answer__c, Related_Question__c from Survey_Option_Table__c where Related_Question__c =: questList];
        
        List<SelectOption> options = new List<SelectOption>();
          for(integer i=0;i<1;i++)
                 {
                 system.debug('++++++++++++++OPTION BLOCK+++++++++++++++'+optList[i]);
                 options.add(new SelectOption('Option One','Option One'));
                 options.add(new SelectOption('Option Two','Option Two'));
                 options.add(new SelectOption('Option Three','Option Three'));
                 options.add(new SelectOption('Option Four','Option Four'));
                 options.add(new SelectOption('Option Five','Option Five'));
                 }
          return options;
    }
   
   
   public PageReference SubmitSurvey() {
    
    for (Survey_Option_Table__c sqItem : getQuestions()) {
 if(sqItem.Related_Question__r.Selected_Value__c != null || sqItem.Related_Question__r.Selected_Value__c != ' '){
     
               //Inserting The Survey Result
               Survey_Result__c SurveyResult = new Survey_Result__c(
                      Answer__c = sqItem.Related_Question__r.Selected_Value__c,
                      Related_Question__c = sqItem.Related_Question__r.Id
                     );
               insert SurveyResult;
        }  else{

             ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'Please Select Atleast one value'));  
        }

    }
        return null;
