50g

I'm not sure if this will come thru ok, I've never posted code here 
before. I think this is what you want.

%%HP: T(3)A(R)F(.);
'Ke=-LN(Vd*Tr/(D*(1+Vd*Tr)))/(\Gt-T\180)'

Just save the 2 lines to a file and use Kermit to transfer to the 
calc (or use the ascii mode of your transfer program).

I know this doesn't teach you how to enter the equation. It's hard to 
tell where you're going wrong. Usually the problem point in your 
entry is highlighted when the error message is displayed. If you can 
tell us where the highlight is, we might be able to determine the 
problem.

Oh, and for the tick mark in the "t'" I used the alpha/right-shift/U. 
You can't use the regular tick mark because it's used to delimit the 
equation itself. You can find it and the tau if you select the "char" 
button on your keyboard.
