This trick is on removing sub-total when there is only one item on native VFP report. Take a look at the image I grabbed from said Weblogs posting below:
The trick lies with a variable. Create a variable, name it to whatever you like (mine is overall), with the following settings:
value to store = 0
initial value = 0
reset value based on a group
calculation type = count
then of course, tick the release after report checkbox.
Now, on anything that is in the group footer, double-click, click print when tab, tick remove if blank checkbox, then place this condition on print only when expression is true textbox: overall > 1
and that is it. enjoy your report with conditional sub-total printing!
Cheers!
