Apparently im getting this issue when PHPExcel is trying to parse the formula '=_xlfn.LOGNORM.INV(1-$AB2,$AW$6,$AX$6)'

Any ideas of why this is happening? if comma , isn’t the function argument delimiter then what is?

EDIT

according to: http://www.excelfunctions.net/Excel-Lognorm-Inv-Function.html

lognorm.inv is basically just an alias for loginv.. so i tried adding:

'LOGNORM.INV' => array('category' => PHPExcel_Calculation_Function::CATEGORY_STATISTICAL,
'functionCall' => 'PHPExcel_Calculation_Statistical::LOGINV',
'argumentCount' => '3'

to Calculations.php, however this seems to result in the same error. So any other routes of action?

    It’s more likely to be the fact that it’s failing to recognise _xlfn.LOGNORM.INV as a valid function, but throwing a confusing exception…. the Docs folder has a list of all the recognised function names, and whether they are supported by PHPExcel… and =_xlfn.LOGNORM.INV is not listed there
