What's wrong with this PowerShell code?

hello, can anyone tell me what's wrong with this PowerShell code?

Someone made this code for me. Basically,  it use a regex to change some lines from a html file. I think it must be filled with something to work. can anyone correct it, as to work good?

$Content = Get-Content -Path $Path "c:\Users\Castel\Videos\Captures" -Filter "*.html"
 Set-Content -Path $Path -Value $Content

# Get each page as a HTML file/ assign to a variable
 #$Htmltext = (Invoke-WebRequest -Uri $MainUrl)# This is the link to the webpage
 #$HtmlPage.content

foreach($Line in $HtmlPage)
 {
 $GetTitle = [regex] "$RegexForTitle"
 $PageTitle = $FindTitle.Match($HtmlPage)
 $PageTitle.Captures[0].Value
$Title = $PageTitle.Captures[0].Value -ireplace '\<[^\>]*\>'
 } #end foreach file
