I am familiar with using the following code in the calculate event in tables when the instance manager is used to add rows:
this.rawValue = this.parent.index+1;
However, I have a simple form that due to the need to expand the text field, I have used used a subform rather than table. While the instance manager works correctly, the number remains at one for each added instance.
A link to the form is here:

Any help would be appreciated.
