Hello @Rajveer ,

It would be better to define a onChange Catalog Client Script.

onChange function stores both oldValue and newValue as a parameter.

You can hide/unhide other variables basis on change of one variable value.

To achieve this requirement, you can use a onChange Catalog Client Script in ServiceNow

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

var updatedFields = [];

// Check if Manager field changed
if (g_form.getValue('manager') != oldValue) {
updatedFields.push('Manager');
}

// Check if Location field changed
if (g_form.getValue('location') != oldValue) {
updatedFields.push('Location');
}

// Check if Department field changed
if (g_form.getValue('department') != oldValue) {
updatedFields.push('Department');
}

// Update the 'updated_field' with the changed fields
g_form.setValue('updated_field', updatedFields.join(', '));
}
