Highlights The Check Box In Red

Just wondering if it is possible to put a check box with a macro say in cell C3 that when you tick the box it changes it to green as completed, but after a set time say 2 weeks the check box clears itself and changes the colour to red to highlight that its due again. Also when you tick the check box it inserts a date in another cell say D4 when it was ticked.


Reason for this is am trying to make a spread sheet with different products that require different testing frequency, some monthly some weekly and some fortnightly. At the moment we are just using a white board and staff just tick task completed problem is they need to check when last done especially when test required is of every 2 weeks and people forget.

If I make a spread sheet and it highlights the check box in red like I want to above at least it will give them a visual reminder that it is due.
