[rules-users] How to put "Power" in Formula box of THEN ?

[Michael Anstis]

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.
