I am trying to use PHPExcel to dynamically calculate certain values. The logic is incorporated into an Excel worksheet. I can set the cell values and retrieve them and I can retrieve the outcome of simple calculations like =IF(SUM(B7:B8)=1,"GOED","FOUT")
But if I try to getCell()->getCalculatedValue of a cell with this formula =SUM(Resultaten!G755:G20754) I never get a result and my page never loads, it just gives a server time out after a while.
Is there any problem with these kind of formula's?
All help appreciated,
