I all, I need some help with Excell. I need to take a log (logarithmic) of some results to base "e", but Excell is screeming errors at me. I can get it to do base 10 and others easy enought but not "e", any ideas?

Alternativly, does any one know the value of the constant "e" and Ill input this instead. (IIRC its about 1.6 x 10^-6 but I need to be exact).

Thanks all!

e is about 2.78 (click)

You should be able to use the ln() function to get natural logarithms.
