     name: null,
     job_title: null,
     emailRules:/^\w+([.-]?\w+)*@\w+([.-]?\w+)*(\.\w{2,3})+$/ //Valid Email Match
  methods: {
    checkForm:function(e) {
      this.errors = [];
      if(!this.name) this.errors.push("Name required.");
      //Email validation for valid email address
      if(!this.emailRules.test(this.email)) this.errors.push("Please Enter Correct Email.");
      if(!this.job_title) this.errors.push("Job Title required.");
