Fixed with git commit 5762cc5b, these help strings are case sensitive, And/Or, and had one bracket typo. I didn't change the help strings but they Could be better as you can use the function or an infix operator And(x,y), x&y, Or(x,y), x|y. Clicking the toolbar buttons inserts & and | which are more generally useful as you can easily chain a set of tests.
