I do not see anything attached. You can post images, but you cannot attach files.
MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here:
XL2BB Add-in
Note that there is also a "
Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.
Without knowing what your values are and what you want to return, it is hard for us to determine what the issue is.
Note that when subtracting dates or times, it is important to understand how Excel actually stores dates and times.
It actually stores them as the number of days since 1/0/1900, and time is just the fraction of a day.
So dates and times are just numbers in Excel with date/time formatting applied.
You will probably need to apply a format to your result cell to see it presented the way you want.
