Thanks can you see what I have done wrong?

Tried also adding this code, however can't seem to get it work, I'm not a programmer so might be something simple!

if(OrdersTotal())
   {
         if(!OrderSelect(0,SELECT_BY_POS,MODE_TRADES))
         Print("unable to select order");
         double op =OrderOpenPrice();
         int type = OrderType();
         double lots = OrderLots();
         int ticket = OrderTicket();
         if(lots == LotSize)
         {
         if(type == OP_BUY && Bid-op > (PartialClosePips*pips))
            {
               if(!OrderClose(ticket,lots/2,Bid,30,clrGreen))
               Print("failure to close order");
            }
      else if(type == OP_SELL && op-Ask > (PartialClosePips*pips))
            if(OrderClose(ticket,lots/2,Ask,30,clrRed))
            Print("failure to close order");
         }
   
   }
