Thank you for the resply.

Tried this: AND(AF$7=$O15,AF$7<=$P15) still slow

Tried this:
=--AND(AF$7=$O15,AF$7<=$P15)

Excrutiatingly slower.

How could such a simple function be such a drag?



and

=--AND(AF$7=$O32,AF$7<=$P32)

Thank you for your response. Yea, did that.

I have posted a new WB: http://uptonroadpress.com/music/
other costs building 0609 c test 2c.xls

I have localized the issue. It is the AND part of the formula.

I split the WB into 3 files.

The AND comparison is very slow, and creates unreadable files when copied
many times at once..

I replaced the AND with a double IF. Same result.

The and determines if 1 number is between 2 others.

The new example has the AND and the IF formulas:

=IF(AND(AF$7=$O15,AF$7<=$P15),1,0)

=IF(AF$7=$O32,IF(AF$7<=$P32,1,0),0)


The challenge is to copy the formulas in column AF for the remaining
column
headers.

Hi

Try changing your calculation mode before doing the copying
XL2003 ToolsOptionsCalculationManual
XL2007 Formulas tabCalculationCalculation OptionsManual

Switch back to automatic when you have finished your copying.

This file is found he http://uptonroadpress.com/music/

This is making me crazy.

I want to finish this workbook in my lifetime.

I need to copy the formula cells to fill 72 columns.

I have to copy about 1 percent of the formulas and paste to 4 columns
each time to avoid a damaged sheet.

I then save, and then close, and then open. Often the sheet is
corrupted.
Then I open the previous worksheet and try again.

I have tried 2003 and 2007. 2007 takes 2-3 times to load, copy, save,
and
scrolling is torture.

Thinking the sheet had a fundamental error I created a new workbook
and
copied the non-formula parts and used formulas saved in notepad files.


I have used 2 computers: 1st uses vista, 2 gig cpu, 2 gig ram, The 2nd
is
a dual-core 2.4 gig cpu with 2 gig ram, xp sp3. Very few programs
loaded,
no AV, etc.,....

This is very annoying.


This page is from a larger workbook that has 6 other pages with 72
columns of formulas. The others are not quite as complicated. But the
workbook loads quicker than this one page workbook.
