...and within that "Perl style" loop, insert the "pseudocode" you wrote above: "i need to subtract first row second column from array1 with first row second column from array2 and goes on for all the rows assign the difference to a variable" Two arrays, subtraction operation, assigning the difference to a variable. I'd say you are more than halfway towards a solution. :)	[reply]
