After all the values have been stored, the operators do their work in calculating the final solution. If you notice below, the values in the comments are what the literal version of the equation is made up of; (x2-x1) + (x3-x2) + (x4-x3)= y. In reference, if the snippet `n-j` and the other variables were converse, the answers came out to be opposite from each other, as in the absolute or negativity value. PHP Code: ``` function jah(){var PH = document.getElementById('myDiv');if (PH)PH.innerHTML = "?";}//end of jah functionfunction fourFunction(){var n=prompt("What is the first value?","0");n=parseFloat(n);if(isNaN(n)){alert("This input cannot be parsed into a number.");return;//x1}elsevar j=prompt("What is the second value?","0");j=parseFloat(j);if(isNaN(j)){alert("This input cannot be parsed into a number.");return;//x2}elsevar k=prompt("What is the third value?","0");k=parseFloat(k);if(isNaN(k)){alert("This input cannot be parsed into a number.");return;//x3}elsevar v=prompt("What is the fourth value?","0");v=parseFloat(v);if(isNaN(v)){alert("This input cannot be parsed into a number.");return;//x4}elsevar u = n-jvar q = j-kvar s = k-vvar b = u+q+svar MD = document.getElementById('myDiv');if (MD)MD.innerHTML = b;}//end of fourFunction()

Net Value Calculator 1.0

This script calculates the net value given a range of respective integers.

Create ListReset?
``` I think that the problem lies where the part of the code has the instantiated varaibles, along with their operators. I tried switching them out, reconfigured them, and even had to reference back, but came to no avail. With respect to the algorithm, 1.94, 1.95, 1.95, 1.95 works, but 0, 4, 0, 0 does not work because the solution came out to be 0 for some reason. __________________ Element ID Webs Support Helper Your friendly neighborhood Taroman.
