Hi,
You'll need a macro to sort it automatically every time you enter a new date. First ensure that all the data in A11:Jnn (where nn is the last row) is in an Excel Table named 'Table1' - alter this name in the macro below if appropriate.
Then in the Sheet_Change event add the following macro
To get to the sheet change event go to the Visual Basic Environment (VBE) with ALT-F11, then find the sheet name you're interested in in the Project Explorer window on the left and double click it. In the right hand window click the left had drop down and pick 'Worksheet'. In the right hand drop down pick the 'Sheet_Change' event.
HTH
