In order to build a chart from my pivot tables that shows both a dollar
value, and a number of entries, I've downloaded XY Chart Labels so that I can
use an unrelated cell as the label source.

In that new cell, I have used the following command to generate my label:
="$"&ROUND(VALUE(D28),0) & "/" & VALUE(D27)

where D28 is the $ value, and D27 is the number of entries.

My problem is that the $ value doesn't include the comma in values exceeding
1000.

The source cells show the formatting as I want it to appear on the chart.
How can I get the chart label to look the same?
