Guys

As per screen dump below :-

I'm trying to calculate 'Active Duration', which should be the difference in days from Work Start Date until Today.

My calculation is DATEDIFF('day',[Work Start (Project Task V)],[Today])

as you can see by the results it's clearly wrong, I'm guessing this needs to be a LOD fixed calculation on the Number column ? I've read a few posts but don't really understand what i need to do here ?

Could someone kindly advise ?

Thanks in advance !
