Niek,

Thank you very much for continuing to help me.

As you instructed, I replaced the "=" signs on the Report worksheet, and it
seems to work. However, when I press F9, it freezes. So I do the replace
("=" signs) on Data worksheet, and it freezes.

Could you please educate why we have to replace the = signs? What do you
think the problem is?

I don't know this information would make any different. The formula in the
Data worksheet are array formula (e.g. {(......)}). In the Report worksheet,
there are 3 columns, and all 3 columns are vlookup. The first column is
vlookup straight to the data, and the last two columns are vlookup to the
array formula in the Data worksheet.

For the first column being vlookup straight to the data, after I did the
replace on = on the Report worksheet, the first column populates with data.
The last two columns do not populate anything.

Thanks.

Try Find-and-replace, replacing all "=" signs (equal signs) by "=". Yes,
replace equals sign by equals sign (for the formula sheet)

It wouldn't do any harm to do that for tha data sheet as well

Niek,

By the way, I am using Excel 2003, and I have also tried to use that Excel
file in another computer. I had the same problem.

Thanks.

Good morning all,

I have an Excel file with two worksheets: Report and Data.

The worksheet Data has data where the data are stored, and the
worksheet
Report is retrieving the data from Data to prepare a report by entering
an
ID
number. The data are retrieved using the vlookup formula in the Report
worksheet. The worksheet Data has 130 columns and 14,000 rows (up to)
of
data.

The way it works is I enter an ID number in the worksheet Report. Then
I
press F9 to do the calculation and the worksheet Report will start to
populate the data. Due to the size of Data worksheet, it takes about 2
minutes to have the Report worksheet fully populated.

The problem that I am having is the file freezes after I press F9. On
the
bottom left corner, it shows Calculating Cells: 0% of Data worksheet,
and
it
would not move forward. I also tried to reduce the number of rows
(from
14,000 to 300) to test whether it would help, and it did not help.

I have been using the file for months, and I have never had that
problem
until recently. Recently, I made additions and deletions of columns in
Data
and rows in Report, but the number of rows and columns stay the same
from
before.

Does anyone have any idea of what causes, and how to resolve it?

Thanks.
