      terms: localStorage.getItem('terms'),
      countries: [{
          name: 'Afghanistan',

        this.errors.push('You need to accept the terms!');
      }
      if (this.errors.length == 0) {
        console.log(this.country,this.state,this.terms);
        let terms_of_use = {'country': this.country, 'state': this.state, 'terms': this.terms};
        localStorage.setItem('country', this.country);
        localStorage.setItem('state', this.state);
