Excel has just begun to do the following: if I attempt to enter a column of figures representing dollar amounts, with one- or two digit amounts followed by a decimal point and two places for cents, Excel automatically converts them to calendar dates, including impossible ones (11.39 becomes 39 November, for example). I can prevent this by prefixing "$" to the numerals in each column, but if I do this AutoSum refuses to add the column, so I want to stop the conversion process before it starts. I can find nothing in Autoformat or elsewhere to turn this off, and clicking on "Help" now produces no results at all. Can anyone tell me what to do? John H
