Dumb question alert.

OK got a decent scan showing 21 steps.  Now I'm inputting the values.
 The numbers I got from Photoshop were 12 through 100 in L value.  Do
I enter those whole numbers?  That didn't work.  Nothing was created
when I hit the create curve button. Do I somehow use the Table of
Ideal Densities from the tutorial by Tom Moore and Roy?  Somehow I
think my density numbers are suspect or I have to convert them to
something else.  The values on the UT2-EEnhMatte-cool curve are 0.047
through 1.590.  Sorry but I'm really lost here.
