I am having a problem with a Macro.

I have a set of part numbers in cells F7:M7. I want to Copy/Paste
SpecialValues down to the next available line at the bottom of the
worksheet, (currently line 20) so I want to paste F7:M7 into the blank cells
F20:M20.

Excel does this fine, and the macro records fine. But when it runs it does
not know which data to use. I think the problem is that the location of the
next available line keeps changing (plus one) each time I try to run the
macro.
