How to refer to entire a column in SUMIFs and VBA

[fa2020]

Hi, everyone
I have a code for summarizing personnel work time while it's sensitive to 8 hours shift, means if the user types work time for a personnel in a specific date which their cumulative work time exceeds 8 hours, this code ignores it and just write 8 hours for that personnel in that date. This code was wrote by one of this forum's users, but I want to develop it to my real world problem in excel. In my own real world problem, I have large number of rows, maybe more than 10000 rows. In the last command, you see there is SumIfs object which refers to limited rows (rows 2 to 16). I want to develop it to entire rows in those determined columns. So, there is no need to make any change in the code every time I want to run the code (I update my excel table every week). I don't know how to make such a change in my code. I need to change all references such as R16C2 to the entire column so for large datasets, I don't need to make any change in my code). I'm new to VBA. Please help me to learn.
And if it's possible, Please add some explanation between lines (green texts) so I can study the entire code.

I revised my post. I think it's clear now.

Hi,

I'd use rather ColumnLetterRowNumber than R1C1 notation and use the lr variable, which you already calculated, so instead of:

rather something like:

But of course you could use references to whole columns like

or if you want to stick to R1C1 notation:

But please do test if a number of such formulas do not slow down your file (you declare using Excel 2019, so it shall not be an issue, as excel recalculation engine is now quite effective in "skipping" unused cells - at least there are such rumours).

Can you please explain " & LR & " meaning?

LR is a variable you used in the code. You have declared it as long (long integer) and assigned the number of the last non-empty row of the column A.
It's even visible in a screenshot you've attached to post #1 :-) (declaration in line #2, value assigned in a line #9)


and the "&" signs are used to concatenate constant parts of the formula with LR value (16 for data from attached file).

I know, but why do we use the mark &??
Why do we use two &s and some spaces between them?
