I want to find the difference or elasped time between to times. my
spreadsheet is setup like this:
columnA columnB columnc
START END difference
TIME TIME
22.41.34 23.18.11 =(b1 - a1)

the cells are formattted as time but the value returnd in c1 is #VALUE!

Any suggestions are appreciated.

MrEyes,

Excel reads time as decimal values, so the multiple decimals are throwing it off. Once you tell Excel how to read your data you'll be fine. I'm assuming

part1.part2.part3

translates to

hour.minute.second

If so, use this formula:

=TIME(LEFT(B1,2),MID(B1,4,2),RIGHT(B1,2))-TIME(LEFT(A1,2),MID(A1,4,2),RIGHT(A1,2))

Basically it takes the value in each cell, cuts it up into pieces, and tells Excel that the first two characters are the HOUR, the two characters in the middle are the MINUTE, and the right two characters are the SECOND.
