The TSref is your friend. I didn't read any further than this, because
the last line of TS makes no sense--though the reason why may not be
apparent to you.

If you're going to do calculations in TS, you're going to need to use
the stdWrap property .prioriCalc [1]. But if you /check/ to see what
the TSref actually says about TMENU's 'maxItems' property, you see
that the datatype is 'int'.

This /also/ prevents you from using register:count_menuItems for
maxItems; in order to retrieve register data, a property or object
needs to have a 'getText' [3] or 'stdWrap' datatype.

What exactly are you trying to do? Why do you /need/ to count the menu
items? Tapio might be right about optionSplit being a more efficient
option, or something like this may work for you:

lib.navigation = COA
lib.navigation {
  wrap = <ul>|</ul>

  # First part of menu:
  5 = HMENU
  5 { ... }

  # Second part of menu:
  10 = HMENU
  10 { ... }
}
