I have the spreadsheet above. I am looking at the dates when pickups were made from the store by two companies, company true and company false. For each store the dates are in chronological order so the trues and falses are interspersed irregularly. For the dates from company true I am trying to calculate the number of days since the last pickup by company true.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
fficeffice" /><o
></o>
<o></o>
To do this I am doing a bottom up lookup using the following formula<o></o>
<o></o>
IF(D34=0,IF(E34=TRUE,DAYS360(LOOKUP(1,1/(E$34:INDIRECT("e"&ROW()-1)=TRUE),F$34:INDIRECT("f"&ROW()-1)),F34),""),"")<o></o>
<o></o>
The formula first looks at whether the pickup in the current row is the first pickup from a given company indicated by column d. If it is the first pickup the formula should return a blank cell. It then looks at whether the pickup was made by company true. If it is, the formula should look from the current row upwards for the most previous true and return the number of days between.<o></o>
<o></o>
The problem comes in with row 41. I'm not sure which date the formula is using for it to return a negative number but it shouldnt. It should find the true in the row above and calculate from there. The problem would be resolved if I could change the $E$34 and $F$34 in the formula to the first rows in that column for each store. In other words, for store 1176 it would be $E$39 and $F$39. It would need to do this automatically so I am trying to figure out how to create a dynamic cell reference. Colulmn C shows the number of the first row for each store. Columns I and J show the cells I want to refer to for each row. However, if I reference those cells in the formula it will use I34 and J34 instead of the cell values. So I need to put the function to calculate the cell reference address into the formula rather than have it externally in columns I and J. However when I do this...<o></o>
<o></o>
...1/((address(b34,e):indirect("d"&ROW()-1)=TRUE)....<o></o>
<o></o>
I get an error message. Is there another way to get the correct cell reference or another way to fix the problem overall? Thank you! <!-- / message --><!-- edit note -->
