Dear Tom,

1) Do not use Capital letters as user defined symbols, variables
and etc. In this way you will avoid possible confliction issues.
The symbols E and D are respectively

In:=
Information /@ {E, D};

>From In:=
"E is the exponential constant e (base of natural logarithms), with
numerical value approximately equal to 2.71828."

>From In:=

>From In:=
"D[f, x] gives the partial derivative of f with respect to x. D[f, {x,
n}] gives the nth partial derivative of f with respect to \
x. D[f, x1, x2, ... ] gives a mixed derivative."

>From In:=

Options[D] := {NonConstants -> {}}

2) No help can be given if you don't show your function.

Regards
Dimitris
