Hello @alona3 
Please use this client script for the field 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    // Get the current field value
    var fieldValue = g_form.getValue('field_name'); // Replace 'your_field_name' with the actual field name

    // Define the valid number range
    var minNumber = 6000000;
    var maxNumber = 6999999;

    // Check if the field value is a numeric value within the valid range
    if (isNaN(fieldValue) || fieldValue < minNumber || fieldValue > maxNumber) {
        // Display an error message
        alert('Error! This task is only relevant for Customers with a number range between 6000000 – 6999999');

        // Set the field value to an empty string or another default value if needed
        g_form.setValue('field_name', ''); // Replace 'your_field_name' with the actual field name
    }
    //Type appropriate comment here, and begin script below

}
