Drag to fill Hyperlink help

[PrestonReed]

Hello, I have made a hyperlink to email once a project has been completed.  It works how I would like it but the issue is I cannot figure out how to drag to fill.  I do not want to manually enter in the correct cells for 1000 lines.  

Here is the formula =HYPERLINK("mailto:"&$AA$3&"?subject="&$AB$3&"&cc="&$AC$3&"&body="&$AD$3,"Send email")

I would like to drag down and autofill up to line 1003 

Any help would be appreciated, thank you.

Opps, figured it out. Had relative and absolute mixed up...

You need to use relative reference for rows, e.g. $AA3 instead of $AA$3
