[IDV #AYP-789112]: Crash of Field difference

The IDV can handle different resolutions. However, it looks like you are mixing 
a 2D field with a 3D field. If so, that won't work, even if you select a level 
for the 3D field. The simple difference formula just uses "a-b" which does not 
try to convert a 3D field into a 2D field. However, you can use the built in 
routine "sub" which will do that.

So, just create a new formula (Edit->Formulas->Create Formula). Name it 
something and in the formula field use:
sub(a,b)

Now, when you evaluate that formula you will be prompted for the a and b 
fields. If you are using a 3D field just make sure you also select a level.
