Cat Item: Dynamic variable that calculates the total of 2 other variables

[DevtoSME]

i created a  request for a Copier Request and need help configuring a total variable that updates based on two other variables.

• There are two single text variables:
  • Black & White Pages
  • Color Pages
• I need a Total Pages variable that:
  
  • Automatically updates as users enter values for the Black & White and Color Pages
  • Displays the sum of the two variables

What’s the best approach to achieve this in ServiceNow’s Catalog Item setup. i attached the 2 catalog

black and white client script
function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == oldValue) {
        return;
    }

    // Get values from the fields
    var blackWhite = parseInt(g_form.getValue('black_and_white')) || 0;
    var color = parseInt(g_form.getValue('color')) || 0;

    // Calculate total
    var total = blackWhite + color;

    // Update the total_copies field
    g_form.setValue('total_copies', total);
}


color at client script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == oldValue) {
        return;
    }

    // Get values from the fields
    var blackWhite = parseInt(g_form.getValue('black_and_white')) || 0;
    var color = parseInt(g_form.getValue('color')) || 0;

    // Calculate total
    var total = blackWhite + color;

    // Update the total_copies field
    g_form.setValue('total_copies', total);
}

client scripts but only the black and white script seems to be working and updating dynamically when changed

I figured out the issue. The color CS was for desktop and the black and white was set to all. thank you!
