DOM buy/sell buttons on MT4 giving an error sound...?

 

Hi there,

When I use the Buy/Sell buttons on the bottom of the DOM it just gives me an error sound and won't enter the trade.  I can close an open trade using the "Close" button, but I can't enter one directly from those buttons.  Has anyone had that issue or can anyone help me resolve it?  I tried googling it and I tried decreasing the lot size to a mini lot but nothing works... Thanks for any assistance!
