What I've found is that the code containing "LastValue(X+PREV_PREV)" must be in the last line of
code for the formula and it must be an un-named variable (can be called by Fml() but not FmlVar() ).
Even this might not work in every case but you should try to make the last line of your formula look
like this
Mov(C,LastValue( EMAPERIODS + PREV - PREV ),E);
The following test example works for me.
EMAPERIODS:=ADX(14);
Mov(C,LastValue( EMAPERIODS + PREV - PREV ),E);
