Why can't I get the total row count for my grid field?

Question

I have a Grid field (called 'beneficiaries') that I'm using to hold a list of first names and last names of beneficiaries, but I'm struggling to get a template to output the total number of rows my Grid field's currently holding. I'm able to output the entire field with the currently submitted data, using:

{exp:channel:form channel="beneficiary" return="/next_page" entry_id="8"}
    {beneficiaries}
{/exp:channel:form}

And that works great.

Now I just want to print to the screen the total number of rows, much like:

{exp:channel:form channel="beneficiary" return="/next_page" entry_id="8"}
    Total: {beneficiaries:total_rows}<br />
    Total: {beneficiaries:field_total_rows}<br />
    Total: {field:beneficiaries:total_rows}<br />
    Total: {field:beneficiaries:field_total_rows}<br />
{/exp:channel:form}

Which only returns the following:

Total: {beneficiaries:total_rows}
Total: {beneficiaries:field_total_rows}
Total:
Total:

Am I doing something painfully obviously wrong? I've read and re-read the documentation to no avail, and I have no idea what I could be doing wrong. Any help as to why I can't seem to display the row count would be greatly appreciated.

The grid field is a looping field, so if the field is in fact called beneficiaries, you should have:

{beneficiaries}
  {beneficiaries:total_rows}
  {beneficiaries:field_total_rows}
{/beneficiaries}
