I can't believe I have come far enough with TS to help out someone else
with EasyLanguage.

Yes.  You can't use an expression in a function that requires a time
series variable as an argument.

The Avg function needs a time series, not an expression that has no
history.

Try this instead (typed into the e-mail without testing):

Inputs: Len1(14);
Variables: pro(0), pub(0);
if currentbar > 1 then begin
   pro = EMA(pro[1], Open - Close[1], Len1);
   pub = EMA(pub[1], Close - Open, Len1);
   end
else begin
   pro = 0;
   pub = 0;
   end;
plot1(pub, "Public");
plot2(pro, "Pro");

I wish you luck with this.  I wasted a week investigating ProGo and
a lot of variants I invented.  It does indicate some turns, however
it seemed to have more false signals than positive ones.  At best
it's a set-up, not a signal itself.
