How to get a Comment for my last MFE

[Tweeker]

Im trying to get a comment of my last MFE and i cant figure out how to do it.

Ive done this. Probably all wrong but, please help.

double OpenPrice;

   double High[];

   ArraySetAsSeries(High,true);

   CopyHigh(_Symbol,PERIOD_M1,TICK_FLAG_ASK,PRICE_OPEN,High);

   OpenPrice= ArrayMaximum(High,TICK_FLAG_ASK,PRICE_OPEN);

   Comment ("Open Price 1-Open: ",OpenPrice);

What should i change?
