Are you wanting to put a limit price in lower than the ask? What are you attempting to do? Right now the price is at .1285. If you put a limit order in for .1285 it'll execute right away as there are shares for sale. If you put a limit order in to buy at .1284 it would have just executed as the price dropped to .1270 crossing the limit line at .1284. The way I remember is that there's a line at each limit price and the order will only execute if it goes through or drops below your limit price.
