Hi Freddy,
The short answer is "yes", but due to some unfortunate features of
BinGO it isn't easy. Basically the reason you can't use the xx_1 column
is that BinGO writes that column as a String, not a number. What you
need to do is to create a new column (of type Integer) and use the
equation builder (the f(x) in the tool bar) to create the equation
"=VALUE(xx_1)". That will take the contents of column xx_1 and convert
it to a number. You can then use that column to set the color.
