Glenn,Should have figured out earlier, sorry :-)Your code:(A:PLANE LATITUDE, degrees) (>L:LAT1, degrees)The needed code: (* You need to put this here *) (A:PLANE LATITUDE, degrees) (>L:LAT1, degrees) (* And this here *)...Rest of the codeOtherwise your LVar will always return 0 no matter the unit because the assignment is ignored.As simple as is :-)Tom

Tom,Bingo!Now, I can keep what little hair is left.I thought it had to be something simple. Even though I'm new to XML I was certain it wasn't a units problem because I could not get a G variable to work either.Thank you so much. Glenn
