There's no major difference in the implementation of scripts between
Acrobat Pro and Acrobat Standard, definitely not if all that is involved is
the calculation of some fields. You need to make sure that the other people
are in fact opening the files in Acrobat and not some other software, and
of course that JS is enabled.
For further tips you'll need to provide more information about the exact
nature of the problem, any error messages, and the exact code you used.
Ok, how do you make sure that JS is enabled? Is it in the preferences dialog box?
his.getField("MyJSWaringingField").display = display.hidden;
