Thanks, Sietse, but 
local function getdeltapage(tag,n) 
seems to mess up \definenote (the error appears when running context --make). 
And if one plows ahead anyway, the original error remains.

Three functions are defined directly above:

L297: local function getsymbolpage(tag,n)
L307: local function getnumberpage(tag,n)
L317: function notes.deltapage(tag,n)

There is no reference to /\<deltapage/ anywhere (`\<` is a word
boundary), so I suggest turning L317 into
    local function getdeltapage(tag,n)
and see whether that solves your problem. I can't test it myself,
lacking a minimal (non)working example. (They should be called Minimal
Illustrative Examples, really, or Minimal Complete Examples. But that
ship has long sailed.)

Cheers,
Sietse
