I tried the examples from last week's article about conditional formatting and it worked well. I tried this expression under "Color":
=iif(Fields!TOTAL_QUANTITY.Value>10, "Red", "Black")
and the following under "FontWeight"
=iif(Fields!TOTAL_QUANTITY.Value>10, "Bold", "Normal")
to get Bold Red when the quantity exceeds 10. 
Now ........ how can I get conditional formatting to work if a drilldown toggle (+) is selected??? 
Thanks for your help ... in advance.
