If I understand this correctly, this has nothing to do with -outreg-, -estout- or any other program downstream. The problems are within your own code.

You refer to `var' within your program -regse- without ever defining it previously in the same program. This is not illegal but Stata will interpret the reference to a non-existent macro as an empty string and the result will presumably not be what you want.
Good catch. Several things happen in the main program, where `var' is defined, before -regse- ever gets called. And, -regse- doesn't refer to `var' until it gets to the -outreg- command.

When programs get complicated it is easy to get mixed up on these sorts of things. Again, occasionally tossing in a -macro dir- or -set trace on- command can help you to see whether the program is doing what you think it should be doing.
