    "File Error: Data May Be Lost" (How do i get rid of this)

    I clicked "ok", the data will display correctly, any idea why?

    I am using safari on mac.

      The data can be a different cell, ie, currently it is overriding the cell. Should be:
      $xls->writeLabel(3,0,"TITLE : ");
      $xls->writeLabel(3,1,"BlaBlaBla");
