Please don't refer to people here as "sir". Not only is it overly formal but it also excludes all our female members.
After "Would you mind" (in this context), you need verb+ing.
Check your spelling carefully. If you have the spellchecker enabled on your browser (and set to English), it should have put a red line under "cheresteristcs".
Addressing people here as 'sir' not only excludes female members, but disrespects them, implying that only men are well enough qualified to answer your questions.
