[Help with php widget link]

Hi all,

 

I've got a problem with a php code on my website. I don't know why, but the hyperlink is wrong, because it's taken also the link of the current page, before the one of the page of destination. (see the attachment)

 

 

Where is the mistake?

Thanks all for the help
