Hi All,

I have a custom form_c object which creates a new contact from the form_c.Name fields. Thats working fine, but I can't seem to link the two records via lookup. I'm trying to populate a lookup field to contact on my form object. form.Student__c;

Here is my controller so far:

public class MeritusSignupController {


 public Form__c form {get;set;}
 public String formId {get;set;}
 public Account a {get;set;}
 public Contact c {get;set;}
 public String is_new {get;set;}


 public MeritusSignupController()
    {
    
     form= new Form__c();
     form.Applicant_First_Name__c = UserInfo.getFirstName();
     form.Applicant_Last_Name__c = UserInfo.getLastName();
     form.Email__c = UserInfo.getUserEmail();
     a= new account();
     is_new = ApexPages.CurrentPage().getParameters().get('newform');
     formId = ApexPages.CurrentPage().getParameters().get('formid');
     String userId= UserInfo.getUserId();
     c= new contact();
      
     List<Form__c> formList = new List<form__c>();
        if (is_new == 'true')  
        {
            form = new form__c();
            form.Applicant_First_Name__c = UserInfo.getFirstName();
            form.Applicant_Last_Name__c = UserInfo.getLastName();
            form.Email__c = UserInfo.getUserEmail();
        }
    
        else if (formId != null)
        {
            formList = [Select id, Student__r.Name, Student__c, Read_understand_requirements__c, Applicant_First_Name__c,Applicant_Last_Name__c, 
            Address__c, Applicant_City__c,Applicant_State__c,Applicant_Zip_Code__c, Primary_Phone__c, Secondary_Phone__c, Secondary_Contact_First_Name__c,

            Languages_Spoken__c,High_School_Attended__c,Planning_on_Completing_FAFSA_or_DreamAct__c,Did_either_or_both_of_your_parents_gradu__c, 
            Email__c from form__c where id =: formid];
        }
        
        else 
        {
            formList = [Select id, Student__r.Name, Student__c, Read_understand_requirements__c, Applicant_First_Name__c,Applicant_Last_Name__c,

            Languages_Spoken__c,High_School_Attended__c,Planning_on_Completing_FAFSA_or_DreamAct__c,Did_either_or_both_of_your_parents_gradu__c, 
            Email__c from form__c where CreatedById =: userId order by lastmodifieddate desc limit 1];
        
        }
