I have a surface modeled and analyzed for surface slope.  When I attempt to add a Surface Legend Table, I get the title and column headers, but no data listed.  What have I overlooked?  The model shows the various categories of slope as analyzed but can't seem to get the summary on the table.
Thanks for any help you might be able to give.

some more information on the problem:
I can access and analysis tab on Surface Properties, and can preview the Slopes Table exactly as I have formatted it (editing the style).   However, I cannot view the data in the legend table that I inserted.
 
 

You might have to check your table style to check if the hatch objects for the colours in your legend are on a layer that you maybe have frozen in your drawing?  I think the default, if you are using t he default styles, is layer 0.
