Reactive Form Validation - Angular 2 - Unable to pick a formArray's controls which is in the main form.

createNewASLForm is the main FORM
AslAccount - is the formArray
From Mark up -
<div *ngIf="createNewASLForm.get('AslAccount').get('acctNumber').touched " class="alert alert-danger">
                    Please enter Acct Number
                  </div>

Tried another

<input class="form-control g-remove-margin-bottom" value="" type="text" formControlName="aslFormName" placeholder="ASL Form Name" name ="acctNumber" required>
<div *ngIf="createNewASLForm.controls.AslAccount.controls.['acctNumber'].hasError('required') && createNewASLForm.controls.AslAccount.controls.['acctNumber'].touched" class="alert alert-danger">
Please enter Acct Num
</div>

Also need to add an entry for 11 numerical vals only....
           



Same this works for standalone controls in the main form
 <input class="form-control g-remove-margin-bottom" value="" type="text" formControlName="aslFormName" placeholder="ASL Form Name" name ="aslFormName" required>
              <div *ngIf="createNewASLForm.controls['aslFormName'].hasError('required') && createNewASLForm.controls['aslFormName'].touched" class="alert alert-danger">Please enter ASL form name</div>



Any help or pointers is appreciated.


Tried this one too...
Used this one too in the markup
<input class="form-control g-remove-margin-bottom" value="" type="text" formControlName="myAcct"   required>
<div *ngIf="myForm.get('SomeAcct').get('myAcct').touched " class="alert alert-danger">Please enter Acct Number</div>
           

Kept throwing errors.
