in this case, the data is extended attributes (water quality sampling for MCL's) against existing wells. Since the I'm attaching to a .SHP from the state well data set, I'm intending to perform a join to stylize points based on the sampling results. so, I haven't tried to add points by their coordinates. When I have some time, I'lll try & let you know what happens.
I was finally able to connect to the excel file and map the points.
There was a duplicate point in the spreadsheet that I missed. Created another column with IDX(index) and everything works now.
Thanks for your input.
