Importing a hyperlink wont work

hello!

This plugin is the first one of many wich succeeds in importing a datasheet.

But I get stuck when trying to import hyperlinks.

The import of featured images goes well, but plain affiate-links to custom fields wo nt work.

any clue what might be the problem?
