Macro to select fixed amount of cells to the right and left

Hi all,
I know this is relatively straight forward but I can't get it to work properly.

I basically want to have a macro which selects 16 cells from the same row.

When I select a cell in column B - i also want to select 14 cells to the right, and one cell to the left (as well as cell in column B) - I just can't get the macro right.

The row can vary - hence why I can't specify the same cells in my macro.

So if I click in cell B10 - I want the macro to select A10:P10.
If i click in B48 - I want the macro to select A48:P48

Thanks in advance

That doesn't select the cells though, it just flags up a message box.

I need to select the cells (to be copied, cut, deleted etc) based upon the row I am currently in.
