If $e=-2.2 and $b=6.3 then $t should equal -4.04921

and exp($t) should equal 0.017436

Oops Shawn, I should have read your post more carefully. Trying to do 2 things at the same time doesn't work. What you got is good. Within the accuracy of the function you returned "3.3". This is good.

Maybe you have a newer version of kixform then I have. The same line seems to return nothing for me.

NTDOC,

I fixed a foolish coding error in the function but I doubt this was the issue.
