Hi,
Need to redirect this url
http://{siteurl}/--/some-text-is-here
to this url
http://{siteurl}/index.php/component/joomd/real-estate-egypt/newsearchresults?searchtxtbox=${b}&Itemid=509
where ${b}= some text is here
Notice I have replaced the hyphen with space

Here is what I did
From Url: ^/--/[a-zA-Z0-8-]
to url : http://{siteurl}/index.php/component/joomd/real-estate-egypt/newsearchresults?searchtxtbox=${b}&Itemid=509

Request only box is checked

Place holder as follows
p={path}
c={preg_subject 2,${p}}/--/([a-zA-Z0-8\-]+)/i{/preg_subject}
b={str_replace '-',' '}${c}{/str_replace}

But I cant get it to work, where is the wrong part.
Thank you for your help.
Regards.
