Weird Problem - With adding Item to cart

[BrokenChaos]

When I add an item to the cart, it doesnt add it.
So when I try a second time it does add it.

Ive tried this multiple times now, with the same results.

The most annoying issue is that Payment Methods are not showing. Ive read the forum posts and nothing works.
What do I do?

I have a website that is not making me any money, because people cannot buy my products 

I wish I was as clever as you lot, then I could solve problems and keep making an income. So what do I do now?

Sorry that I am not clever, but if someone could help me finish the cart, I would be very grateful.

Thanks to the chap before that helped me a bit... I found a jquery plugin that helped me a LOT.... I just need this last bit of help 

The website is www.thailandairsoft.com

Looks like items are now adding to the cart first time now...

You still cannot select payment options... However, it will let you checkout and THEN it will ask you for payment option, which is useless at that stage, as its not on the overall item/total screen, so you cannot see what the total cost is (there is a cost with one of the selected payments)...

ANybody know what is wrong and how I can fix this???

I am so close to getting it all working properly... I really need some help guys/gals
