Gas Safe register - Online Notification

[bert large]

Hi,
I have been trying to notify some appliances with GSR online & have run into dificulty

Admittedly I have saved them up for a while so thought i had better notify them now. What happens is :- The process all goes well & the notifications are all done sitting there waiting for payment, after I put in all the card details it says click to pay, which I do them goes to a Lloyds TSB page for registering cards or something. Do I need to complete this ?
This is as far as i get ?????????????
Can someone point me in the right direction from here. I managed to do it all successfully last time I did it earlier in the year

think you will find its a security measure from your card issuer, "verified by visa" or something similar, the amount you want to put on your card is probably above the "safe" limit, so you will need to complete it or do them in smaller quantities.
