NX 7.0 - base shell element thickness off nodal coordinates?

[score33]

The object I am trying to mesh has a thickness that varies in X and Y, I'm looking to enter this equation into the properties somehow so that I don't have to manually specify the thickness.

Currently I have to export the *.dat file, edit with excel to get the right thickness, then run the file.

Is there a way to do this inside of NX so that I cut out the excel step?

thanks.

Forgot to mention that I'm trying to use the Form Field in the Mesh Associated Data.

the equation for my thickness, based on the X & Y coordinates, has squared terms for the X and Y variables and gives me a dimension error when I try to enter in:

ug_var("x")^2

but works fine when just adding or subtracting values.
