Hyperlink adding directory info??

I am using this code so every time I need to add a hyperlink I can add to a list easily and automatically. It used to work fine but now it adds the workbook directory to it. If I enter the website as "www.yahoo.com" I get an error when I try to click on the hyperlink because it shows to be linked to "File:///G:\New Folder\www.yahoo.com" When I try to edit hyperlink it shows "Existing File Or Web site is clicked,and address is "www.yahoo.com"???? What am I doing wrong?

HLink = InputBox("What is the website")
Sheets("Grab Lists").Activate
Range("M500").End(xlUp).Offset(1, 0).Select
ActiveSheet.Hyperlinks.Add Anchor:=Selection, Address:=HLink, TextToDisplay:=CellText

Please help this is driving me crazy!!!

Thank you in advance

UPDATE: I figured it out.... turns out I MUST enter HTTP:// first. Sorry and thank you.
