I try to use the 2Checkout Payment Extension Magento I got the error to process Payment the console print like this. Anyone knows the issue.
prototype.js:828 Uncaught TypeError: Cannot set property 'href' of undefined

Finally, I fixed that error. I changed the code on observer.php It's located in /app/code/local/Craig/Tco/Model / observer.php
under if (Mage::getStoreConfig('payment/tco/inline')
if ($$("a.top-link-cart")) { //old observer.php line 70
I changed this to
if ($$("a.top-link-cart").length) {
and also samething in else
if ($$("a.top-link-cart")) {
to
if ($$("a.top-link-cart").length) {
