I'm wanting to calculate the Elapsed between the start and end date/time. I can achieve this in column C. But as soon as I attempt to excludes weekends in column D the results isnt correct. What am I doing wrong??

Help very much appreciated. Thank

How about:
=MIN(INT(B2)-INT(A2),NETWORKDAYS(A2,B2))&" Days " &TEXT(MOD(MOD(B2,1)-MOD(A2,1),1),"h ""Hours"" m ""Minutes""")

=MIN(INT(B2)-INT(A2),NETWORKDAYS(A2,B2))+MOD(MOD(B2,1)-MOD(A2,1),1)

Format as a number with the decimal places of your choice.

Hey @Scott Huish - thanks again, now that I'm comparing the decimel values i have spotted something thats not quite right.

I have a new example in row 7, that spans across 2 weekends. however i'm only seeing 3 days being taken off? should be 4

Not sure I see the problem, if you made row 7 the same time in both cells, you would see that it's 7 days, and if you look at a calendar, it's 7 days. (4 weekend days removed, Dec. 2 & 3, Dec. 9 & 10)
Dec. 1, Dec. 4, Dec. 5, Dec. 6, Dec. 7, Dec. 8, Dec. 11

The problem is you're comparing it to subtracting dates which is not inclusive of both dates, so if if you subtract Jan 2 from Jan 1 you get 1 to include both dates you would have to add 1, so for your comparison to be correct your formula in D2 should be =B2-A2+(B2-A2>=1) so that it will ad 1 for date differences that are 1 or more days apart
