Excel/help in functions


i made a simple function which displays the last time the value in a particular cell is modified. the functions works but also when just when i filter the sheet to find particular no even though i havent changed anything. it again updates when i remove the filter(updates also when i filter through other columns). how should i improve my code
Code :
Public Function Lastmodified(c As Range)

Lastmodified = Now()

End Function

Hi Salem,

I am unable to duplicate your problem. For me it only updates when the cell c changes.  When I filter columns on the sheet, add/or delete filters the time does not update.

I suggest you email your file to me so I can see what is happening and debug it.  My email is ExcelVBAconsulting@gmail.com.
