I have an odd exception I cannot trace the root of, Using version 1.7.4: System runs nicely through part of the equation in the cell then just gives up throwing an exception.
Having played around quite a bit with this I wonder if its a problem recalculating the same cell value for a second time as the problem seems to occur when the system is about to recalc the Course_leadership_min for the second time in the final clause of
the second IF underlined / bold below. Alternatively have I just hit the nesting limit or some stack problem?
Any thoughts anyone?

Details:
This is the equation:
=IF(C12<>0,((V2TM_lecture_points*E12+(((INT(C12/(V2TM_seminar_Split_count+(V2TM_seminar_Split_count/5)))+1))*V2TM_lecture_points*F12)+(C12*V2TM_individual_student_assessment_points)*G12)*(D12/Base_credit_value))+IF(B12<>0,(B12*(Course_Leadership_min+(((Course_Leadership_maxCourse_Leadership_min)/Max_group_size_for_scale_calcs)*C12))),0),0)
and here is the output from the getCalculatedvalue() echo's

You'd normally only get this exception with a formula that hasn't parsed correctly, but it's the fallback error, where the parser can't identify what the problem actually is.
Having played around quite a bit with this I wonder if its a problem recalculating the same cell value for a second time as the problem seems to occur when the system is about to recalc the Course_leadership_min
for the second time in the final clause of the second IF underlined / bold below. Alternatively have I just hit the nesting limit or some stack problem?
This wouldn't normally be an issue. The default setting is that PHPExcel will cache the calculation results for each cell, so subsequent requests that reference the same cell will read the cache rather than recalculate. There is a time limit for this cache,
but I don't think that's likely to cause this problem.
Is it possible for you to try this with the latest SVN code? It provides better logging information within the Calculation Engine.



Hi Mark.
Many thanks for the reply. Tried it with the latest version of cell.php and calculation.php as the full new version gives me other headaches. I restored the remmed out echo / print lines and added MWS at end of error call in calculation function to be sure
it was the source of the error and by the looks of it the line 3300 is indeed where the problem is spotted:
3300 if ($stack>count() != 1) return $this>_raiseFormulaError("internal error MWS");
Here is the final portion of the output I get when I run it all:

Just to confirm the actual spreadsheet works fine so at least as far as Excel is concerned the equation is well formed enough, but there may be a wrinkle I have missed.
Not sure this helps any further thoughts?
