Does any one know the formula to calculate top half rows/ bottom half rows of column D,
Simply by selecting ALL the rows in column D, as shown in the image

(I am not looking for the =SUM formula )

i have several tables like this and sometimes the number of rows may be odd/even

Thanks! I tested it and it works well now...

i will be pasting this formula into several excel sheets,
on every sheet, its going to be different columns and rows

By any chance we can make it work by changing just 1 time on the formula where "D1"&":D" and "D1:D7" appears ,
so that i do not have to change 4 times on the formula whenever i paste the formula into another excel sheet ?

You can use cell references in the formulas and/or named ranges but the best solution would require
an understanding of your challenges.

to sum the first half of column D

=SUM(OFFSET(D:D, 0, 0, COUNTA(D:D)/2, 1)

to sum the second half
=SUM(OFFSET(D:D, COUNTA(D:D)/2,0, COUNTA(D:D), 1)

Considering
a) you have data below the relevant range
b) with an odd number of entries, you want to split the mid number
c) using mikerickson's suggestion and dividing the mid number by 2 try

=SUM(OFFSET(rColE,0,0,COUNTA(rColE)/2,1))+ISODD(COUNT(rColE))*MEDIAN(rColE)/2

i do not understand what is the function/meaning of ISODD , so i modified your code for "Column E, 1st Half" to the following instead :
=SUM(OFFSET(E1:E7,0,0,COUNTA(E1:E7)/2,1))+MEDIAN(E1:E7)/2

This is what i am getting now (i still have no idea where is the html maker function, so i am pasting an image here ) :

Your questions
1. IsOdd See Excel's Help. True is equivalent to 1; false is equivalent to 0.
2. Try reviewing/evaluating the components of the formula. You can also use Excel's Formula Evaluate.
3. MrExcel's HTML Maker see the top posting in the forum Suggested Add-ins.
