In an IF statement, Excel sees blank cells as 0 (zero)...but it will NOT see cells with a space in them as zero. The formulas that are linked to another workbook won't update til you open the workbook and say Yes to Update the Links.

Basically if this cell = this value then I want this output. I need to write this in a function that can be used in other spreadsheets. I have written the function and it works but here is my question. How does Excel treat a blank or empty cell? is it's value '0' or "" or null? Also when I am working with this and I modify the function, is there a way to recalculate the spreadsheet? After I change the function the values are not updated. -Anthony ************************************************************* You are receiving this mail because you subscribed to mso@xxxxxxxxxxxxx or MicrosoftOffice@xxxxxxxxxxxxxxxx To send mail to the group, simply address it to mso@xxxxxxxxxxxxx To Unsubscribe from this group, send an email to mso-request@xxxxxxxxxxxxx?Subject=unsubscribe Or, visit the group's homepage and use the dropdown menu.
