I believe you were trying to say "hold on a second, I've gotta place something for the radar section, a lampshading." in your previous comment, correct?
The contribution you made was grammatically correct save for one part at the beginning with "the a" (drop the "the"), so I advise you carefully review all of your edits before saving anything from now on.
I also found a link you should check out for more help:

Also, you don't have to say if you don't wish to, but where did you get in trouble for grammar issues before. Regardless whether you wish to say anything on that subject or not, I consider myself a reasonable person, and you are clearly editing in good faith, so please be assured that I will be willing to continue helping you until this grammar issue is resolved, and I will not hold any previous experiences on other sites against you.
If I'm not available, you can ask another admin for help if you need to.
