richTextBox7.Clear();
foreach (double SuppA in list9)
{
richTextBox9.Clear();
foreach (double wee in list8)
{
a= (wee / e) * 100;
richTextBox9.AppendText(string.Format("{0:n2}", a) + "\n");

conf = a/ (SuppA / e);
richTextBox7.AppendText(string.Format("{0:n2}", conf) + "\n");

lift = conf / (SuppB / e) / 100;

can u provide more clarification... ?
the info u provided is very abstract...

provide an example..

Is, the lists u have given in loops i.e., list8,list9,list10 have the same length or different. Can u ur description more clearly?

list box8 contain :
5
6
5
5
4

list Box9 contain :
7

listbox10 contain:
6
7

1st of all, i need find out the answer a, for answer a, the formula is ,a= (wee / e) * 100
after that, i need use answer a to calculate conf. the formula for conf is ,conf = a/ (SuppA / e)
lastly, i need use answer conf to calculate lift, the formula for lift is ,lift = conf / (SuppB / e) / 100;

now my problem is the answer for conf and lift loop many times.how can i correct it ?
my coding has been post above.

what is wee, suppA,SuppB ,e ?? where does it come from?

Instead of foreach loop, u use for loop where u can compare the values, here in foreach loop as the count of listbox9 and listbox10 are more than listbox8, the loop is repeating more times. Hope it helps to u.
