So i replaced ; with , and now this error seems to be corrected
But i have another one : <b>Warning</b>: mb_substr() expects parameter 3 to be long, string given in <b>C:\wamp\www\copix_svn\utils\phpexcel\Classes\PHPExcel\Calculation\Functions.php</b> on line <b>5195</b><br
It seems to be the MID functions which has a problem because of the third params. I use MID 2 times, the first time the third param is the LEN(c19))-MID(c19;1;FIND("-";c19;1)-1) and the second time it is inside the first time : MID(c19;1;FIND("-";c19;1)-1)
It worked in previous version, any idea ?
