Issues with registering domains and transfering

Hello,

I am extremely new to whmcs and I am just playing around configuring it very slowly.

I am having trouble registering domains and transfering.

I have configured my packages, setup me registrar(resellerclub), and set the domain TLD pricing. When I try to order a package, after I confirm the domain is available. I selected the pricing. Then it brings me back to the same page. Nothing ever happens, it also does this when I am transferring. Does anyone have any insight to why this is happening?
