#1 ctoggle with score

[Anonymous]

I tried to calculate a f-table with
f 1 0 [2^[gensize]] 10 1
where [gensize] define is in the tk_interface:

ctoggle gensize "Gen size" -value {2 4 8 16 32 64 128
256 512 1024 2048 4096 8192 16384 32768} -init 256

and I get the error in the orc file:
;INIT ERROR: Invalid ftable no. 1.000000
Why are the varibles defined as [variable] in the
score? [x] is already defined by c-sound to calculate a
amthematical expression x.
f1 0 [2^2] 10 1
should work in cecilia but i get the same error.
