adding only positive numbers
I created an ammoritization schedule for mortgage loans.
I have the following columns: A B C D E F Month Principal Balance Payment Interest Principal Outstanding Balance There are 360 months (and thus, 360 rows below the above row) and I SUM columns C, D, E, respectively. The problem is, if I create a table of only 240 months or 200 months, it will insert ( ) for everything past this new month (i.e., I zero out at 240 mos, but the table continues on to 360, adding all the negative numbers for 241-360), and give me a skewed total. How can I get it to only SUM the positive numbers, or better yet, don't display anything past the chosen term? Thank-you, and please let me know if any other information is needed. Jacob |
Jacob, one way, use sumif, like this =SUMIF(A:A,"0")

maybe you could adjust your formula to look for a negative:
=if(somecalculation<=0,"",somecalculation) I kind of like the way Microsoft did it in their template. You can find lots at: http://office.microsoft.com/en-us/te...317261033.aspx And just look at all that's available: http://office.microsoft.com/en-us/te...s/default.aspx Jacob wrote: I created an ammoritization schedule for mortgage loans.
