Using Variable Cell Value As Worksheet Name

I have a macro on a button click that copies and pastes the template worksheet into the same workbook on a dialy basis, i would like to rename the "template" copied file to a unique worksheet name based on a date ie 31_3 (31st march) and so on, the cell that provides the date changes on a daily basis to the next one, however when the script runs it uses the original macro recording date rather than the new one!, the changable cell is AS2.
