Displaying info
 

I have a spreadsheet that has a running total of data
based on adding info from 3 columns. I only want to
display the info that is less than or equal to 38 and the
corresponding rows. If the total is greater than 38 I
want to either hide or change the font of the text to
white. I have used conditional formating, but I don't
know how to suppress the entire row.
