Is it posible, inside the NOTES section inside the INVOICE to call a particular field?
For example, inside NOTES I want to add something like:
Remember that the subtotal “____ (Reference to the subtotal)” must be paid in advance and the Tax “___ (Reference to the tax)” must be paid to a particular account.
The exchange rate is “____ (exchange rate)”
Is this possible? If so, where can I find the shortcode for each instance.
