AHK: convert text selection to hyperlink with clipboard as target

Using Autohotkey to achieve this behaviour:

• copy URL from browser
• select text in word doc
• press keyboard shortcut
• AHK converts selected text to hyperlink with clipboard as target.

This is what I have so far:

^b::
wd := ComObjActive("Word.Application")
url := %clipboard%
wd.ActiveDocument.Hyperlinks.Add(wd.Selection.Range, %url%,"","","")
return

I've tried many other variations, but alway get the error that the url variable contains illegal characters.

Any ideas? Thx!

Variable names in an expression are not enclosed in percent signs.

^b::
    wd := ComObjActive("Word.Application")
    url := clipboard
    wd.ActiveDocument.Hyperlinks.Add(wd.Selection.Range, url,"","","")
return

or

^b::
    wd := ComObjActive("Word.Application")
    wd.ActiveDocument.Hyperlinks.Add(wd.Selection.Range, clipboard,"","","")
return
