Hi Lee, Just now (12 years after you sent this post
) I found that this error occures when an "Excel" cell is containing a numeric value with a "point" as "period".
AFAIK it is not Excel related problem. It is due to "Windows" settings when "/" is assigned to "Decimal Symbol".
Enclosed Clip shows how I got rid of the error. But I don't know why this incompatibility occures. When using "/" to write a decimal number like1.5 obviously it must be typed as: 1/5, but surprisingly Excel changes that to 0/2 (It divides 1 to 5).
I am sure you can write a Visual LISP code to solve this problem automatically.
