It's ready in vb.net (see screenshot). the code have just 22 lines including spaces and four comments, it's a very clean code. I'll PM you to send the details of the payment. Check if the amount in the screenshot is correct (I possess almost no knowledge of financial matters so I'm not really sure if the FINANCIAL.PMT function is working well) Btw I'm new in the forum so as you may not trust me, if you need it I could make a video to show you that it's functional before payment.
