What do you mean "didn't work"? Did it say FALSE?

Check with the LEN function for the correct length of the number (or
actually the text, I'm sure); there may be non-printable characters in the
cell. Check the CLEAN() and TRIM() functions.

The ISNUMBER() didn't work, and I've double checked the comma; all is
okay there. Just a note, I've imported this data from a online
cellphone bill, and I'm trying to total minutes by phone number. Could
there be a problem because of the format of the other doc?
