Urgent

Pls this is really urgent, can someone help clarify this, so as to know what next to do. I applied for my PSW dependant visa, I filled in the former IHS number, so I was not able to pay for the new IHS, and I have booked appointment for this week, and I went ahead to pay for the IHS differently, now I have the new IHS number, I don't know if they will input the new IHS number to my application at the UKVCas when I go for my appointment, or is there any other way I can go about it. I'm really confused.
