Thanks, Stefan. My table kind of looks like this: 611000,4817200,89.08218 611100,4817200,89.99966 611200,4817200,90.5815 611000,4817100,87.9949 611100,4817100,89.10567 611200,4817100,89.99977 611000,4817000,86.90109 611100,4817000,88.0576 611200,4817000,89.13644
First, I created points from the Table menu. When I try to create grid, I got the error messages saying "Warning: 9*9<>9. Cannot Continue".

Is this true? I think, that's not true. It works with XYZ file too. I think the problem is somewhere when you reprojected lat/long to NAD 83. Grid tool is using for calculation of the row and column MapInfo's SQL "GROUP" command. Something like this: for columns: Select CentroidX(obj) from SourceTable GROUP SourceTable.CentroidX(obj) Into tmpSel columns = tmpSel for rows: Select CentroidY(obj) from SourceTable GROUP SourceTable.CentroidY(obj) Into tmpSel rows = tmpSel Then checked if number of the SourceTable rows is equal rows * columns If SourceTable rows are not equal to rows * columns the problem occurs. I really do not know, how did you transfered one coord. system to another one (you didn't mention about), but try this: open your table as is (it means with lat/long system) save it in NAD 83 open NAD 83 and try to use Grid Tools again Hope this help you.
