Hello,
I have a map with contour lines on it and need to overlay a slope gradient grid with the slope percentages for each grid section over top. The grid is 200ft squares. I have attached an image to show what I need.

Assuming you only have the contours as the source for a surface: I would try making a TIN from the contours then a grid file at your required resolution from the TIN. Next copy the surface grid file to a new grid to use for the slopes and use the Grid File Utilities to convert the copy elevation grid to a grid of slopes and plot the slopes.
Check values in several areas to confirm you are getting expected results.
