I'd try using free-format DRL and breaking the expression down into smaller parts until it works.
I can't see anything wrong with the syntax - unless it relates to the bug Wolfgang said was fixed for 5.4.0 (I *assume* he'd mean FINAL). The advice, as I have given before, would not to use a beta version as it is bound to have bugs in that were fixed for FINAL. I know you use it for the free-format text "Formula" TextBox in the RHS of the Guided Editor, but free-format DRL (with 5.4.0.FINAL) is a suitable workaround.
