minor fixes

Hi, I noticed a stray

element, so I removed it.
Also the same variable was being declared twice in the same scope, so I changed the second variable.
Fairly trivial changes.

oops I should have left these first simple fixes in a separate patch branch, instead I merged them onto my master branch and initiated the pull request from the master branch; now the other changes I have merged to my master branch have been included in this pull request. No harm done, they are still useful enhancements that I put in a separate patch branch and for which I initiated another pull request.
