I have tried adding multiple angular validator arguments [i.e Validators.minLength(8) and Validators.maxLength(12) ] to my form and i cant seem to get it to work...these arguments are attached to the (password and passwordc) instance in the code below. Any help please?

```
   export class signupComponent {
        signupform: FormGroup;
        constructor(public fb: FormBuilder) {
            this.signupform = this.fb.group({
                firstname: ['', Validators.required],
                lastname: ['', Validators.required],
                account: this.fb.group({
                    email: ['', Validators.required],
                    **password: ['', Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')],
                    passwordc: ['', Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')],
                }, { validator: passwordMatcher }),**
                shortbio: ['', Validators.required]
            });

        }
    }
