What i want to do is take data from columns "AA" and "BB" and have them inserted into the columns and rows to the left. The 1st event entered is AA=5 BB=10. AA determines which column and BB determines how many rows to fill. The 2nd event AA=6 BB=12 go to column "E" which is 6 and fill down to the number 12. Now when another event happens to have the same column AA=5 BB=15 column D which is 5 and add a 1 to rows 0-15. There may be as many as 50 events to calculate. If an event happens in the sane column several times it would be added to the data in those cells. I hope this explains. thanks in advance. Mark
