Was that a typo?  You wrote:

Note that in your list of variables in the dataset you include:

inc80
inc81
in82

but in the reshape command you refer to:

reshape long ue inc,

I assume the type is only in the e-mail message, but it is such a small
thing that sometimes only someone with fresh eyes can see it.  Might
that typo be the problem?
