Hello, thank you for this great library. I am trying to use PHPExcel on existing file: input some data into it and then get calculated values from other cells which will be calculated according to the data entered earlier. The calculated values differ from
actual excel if I enter them manually. The result cells seem to give the values that are in the excel file itself before the input  so its like no calc is being done..
The error seem to be in the cells that depend on other calculations which include
vlookup. This is a bit complicated excel file so here is a link to download both excel file and php script.

There also is the original file before convert to excel5 and 2007.
How it works:
Cells F to T 10 are the result which is: TRUE or FALSE.
Inputting values into cells: B7, B8, C7, D7, D8, H to N 7. Also F2 the input is "yes".
Now the calculation on line 10 is made on values on line 14, so the script loops the lines 15115 putting each line in line 14, and read True/False values from line 10 each time.
To get all true on at least a few lines the input should be:
C7  5, D7  0.001, D8  0.0001, H7  1.064, F2  yes.
The script originally is in 2003 format (I think), to make phpexcel work on it I converted it to Excel5 and calculations didn't work as I stated before, so I converted it to 2007 and got whole bunch of errors like:
Warning: strtolower() expects parameter 1 to be string, array given in
F:\xampp\htdocs\xls\PHPExcel_1.7.2\Classes\PHPExcel\Calculation\Functions.php on line
11178
which are from function that takes care of "VLOOKUP".

Sorry for the long post but I didn't know how else to explain it :)
Thanks for your help.
