Hello, ive a service catalog page and some items to order, once user user click on the submit, it shows the error as given in the question. i check the console the following error shows up.

[SCRIPT:EXEC] Error while running Client Script "total amount for ID's": SyntaxError: Unexpected end of JSON input

[SCRIPT:EXEC] Error while running Client Script "total amount for invoice to apply": SyntaxError: Unexpected end of JSON input

How to fix it?

"There is a  java script error in your browser console"
error

The catalog client script use is :

function onSubmit() {
if (g_form.getValue("u_request_type") == "Inventory Adjustment") {
var multiRowVariableSet = JSON.parse(g_form.getValue('invoice_s_to_apply_to'));
var tot = 0.00;

for (var i = 0; i < multiRowVariableSet.length; i++) {
var amount_two = +multiRowVariableSet[i].amount_two;
if (!isNaN(amount_two)) {
tot += amount_two;
} else {
console.error("Invalid amount detected at index " + i + ". Skipping calculation.");
}
}

g_form.setValue("total_invoice_amount", tot.toFixed(2));
}
}

I don't know that this would cause that error, but you have an errant + character in this line

var amount_two = +multiRowVariableSet[i].amount_two;

I have seen an error parsing the value when a MRVS is empty as the native UI returns [] as the value, so I usually break it down like this:

var multiRowVariableSet = g_form.getValue('invoice_s_to_apply_to');
if (multiRowVariableSet.length > 2) {
    var obj = JSON.parse(multiRowVariableSet);
    for (var i=0; i<obj.length; i++) {
    ...

Otherwise, try alerting on the value of (unparsed) multiRowVariableSet - does it look well-formatted, or does it contain a special character that could be throwing off the parsing?
