Question

I keep reciving this error \"Cyclic Reference in Formula\".

When I am trying to download my excel file.

Now when im deleting the \'=\' from formula\'s from m

Answer 1

for me this occured when I specified a column range that was backwards. so instead of E10:E11 it was giving E11:E10 once I put it in lower to higher order the error went away. I was using a =SUM() function and I guess phpExcel and excel can't handle it backwards......
