[Edited]I had to edit because honestly, I'm somewhat perplexed by your code.
But that's neither here or there. To start off you not removing the "onclick" attribute, you are removing a class attribute.

The next problem I see is that the inp element collection starts at index 1 instead of zero. This element collection is like an array in that its index also starts a zero. This will cause other problems like the 1 button not to work when you change over to entry2.

To get rid of the error message I suggest replacing "setAttributeNode" with setAttribute, if you decide to do so you will need to pass the attribute name and value:
setAttribute("onclick", "calculate.entry2(this)").

OK I tried it and it fixed my problem, I think this may be the most functional calculator I've made so far because of you. Thanks.
