WP Plugin Simple 301 Redirects

I recently changed my directory PHPLD site for a wordpress site, in doing so I neglected to think about 301 redirects. Well, I’m trying to use this particular plugin that seems easy enough, but it’s not working for me at all. For instance, my old URL for a page was “https://www.localhoma.com/Jennifers_Hair_Outlet_Sapulpa.html”, and I would like to redirect to “https://www.localhoma.com/clients-and-partners/jennifers-hair-outlet-sapulpa”

If I followed instructions correctly, I put in the request field “localhoma.com/Jennifers_Hair_Outlet_Sapulpa.html” and in the Destination field “https://www.localhoma.com/clients-and-partners/jennifers-hair-outlet-sapulpa”. I am sure that I’m missing something wrong. If someone can enlighten me to my oversight, I would greatly appreciate it. ??

Thanks in advance,

Bob
