Thank you for your help. What I am trying to say is that, for example, I
have sales and their subtotals in column C. Lets say C2-C6 are sales values
for Company X and C7 is the subtotal. THen C8-C20 might be sales values for
company Y with C21 the subtotal and so on. THere are different numbers of
sales values for hundreds of companies with each company having its own
subtotal. I need to find what percentage each sales value is compared to the
subtotal. (The % each company sold compared to its own total) So I would
need to find the % of C2 and C3 and so on compared to C7. But then I need to
go down and find the % of C8 & C9 & so on compared to C21. If there were the
same number of values and then a subtotal for each company, I could do
it....ANy suggestions? Help is GREATLY appreciated!

As I understand it, you want to determine the share of the company's total
volume represented by each transaction. Ignoring the subtotals for a moment,
let's suppose the company name is in column A and the sale amount in company
B, with headers in row 1 and data beginning in row 2.
In c2 you could calculate =b2/sumif(a:a,a2,b:b) and format as a percent.
The sumif totals this company's sales, so the division gives you the percent
of this company's sales accounted for by this transaction.
If the subtotals are interspersed, with the subtotal labels (column A) the
same as the company name, you'd need to multiply the formula above by 2 since
the sumif would total up the individual transactions as well as the subtotal.

In column one I have the names of many companies. Each company has different
sales amounts. so each company is listed more than once (each company may be
listed a different amount of times, depending on the number of sales) I have
sales subtotaled for each company. In the next column over I would like to
calculate the percentage of a value compared to the subtotal. i need to do
this for each group. I could do this if there were the same number of sales
for each company, but how do I create a formula to do this when there are
different numbers of values?
