Customizing Data Forms

Question

I need help with customizing the data forms.
We have users entering percentage values in the form. the total percentage amount in a column should not exceed 100 percent. If it is more than that it should show an error message.
How can I achieve this.
TIA.

Answer 1

I want the code to verify if the user is entering percentages more than or equal to 100. But this particular code is considering the sum of percentages in all rows + columns. But I want the code to verify for all the rows in first column, all rows in second column.
Can anyone help me change the logic in the below code.
function validateForm()
var valid = true;
if (equalsIgnoreCase(formName,"1") || equalsIgnoreCase(formName,"2")) {
valid = validateVariance();
return valid;
function validateVariance() {
var validated = true;
var cellValid = 0;
for (r=1; r<numRows; r++) {
for (c=1; c<numCols; c++) {
var cell = getCellVal(r,c);
if (isFinite(parseFloat(cell))) {
cellValid = limitPrecision(cellValid + getCellVal(r,c),3);
if (cellValid >= 1) {
validated = false;
cellValid = limitPrecision(cellValid * 100,2);
alert("The percentages you have entered exceed more than 100% \n Your Total Percentage is: " + cellValid + " %");
return(validated);
function limitPrecision(value, limit) {
if ((value == null) || (value.length == 0) || (value == missing)) {
return(value);
} else {
return((Math.round(value * Math.pow(10,limit)))/Math.pow(10,limit));
TIA
