Hello, I'm DMacks. An edit that you recently made to Trichloroethylene seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. The infobox fields need actual numerical values, not place-holders or unresolved footnote marks. DMacks (talk) 19:04, 20 September 2021 (UTC)
