When you transfer files containing ChemUnits functions to other computers, Excel automatically appends the full pathname to all ChemUnits function calls. This is a "feature" of Excel, not ChemUnits. If the directory structure containing the Excel program is identical on both computers, this will not cause any problems. If, however, the two computers are set up differently or have different versions of Excel installed, after you transfer a file you will see the "#NAME?" error in any cell with a ChemUnits function. To fix these errors, simply click on the "Update ChemUnits Links" command from the ChemUnits Menu under Excel's ADD-INS tab.
