Hello Jordan,

I don't know anything about IUP (I've never been able to even get it
installed), but from the documentation's examples, it looks like LED is
not linked to Scheme in any way; instead it uses identifiers which are
similar to the identifiers in Lua.  Look at this example:

http://webserver2.tecgraf.puc-rio.br/iup/examples/LED/submenu.led
or the Lua version:
http://webserver2.tecgraf.puc-rio.br/iup/examples/Lua/submenu.lua

This means that "menu-item" is not defined in LED.  Instead, you'll
need to use just "item".   I suppose Thomas chose to use "menu-item"
as the identifier in Scheme because "item" is too generic and would
easily conflict when using other libraries.

Perhaps, if this is too confusing, it may be wise to use exactly the
same identifiers as Lua and LED use.

Cheers,
Peter
