Well that got me past that error, but now I have a much bigger problem.  I
need a way to speed up the geomunion process.  I know I am asking a lot of
this function, but I have about 40K rows and the process to do the geomunion
has been running over 80 mins and still going.  Does anyone have a better
idea on how I can get the same results?  

Please see attached email for original description....

Thanks in advance,
Lee
