Conditional statements in "block" part

Hello everyone,

I have a perfectly functioning experiment that includes a training block and a test block. I wanted to implement some additional instructions in the test block if a participant made 15 or more errors in the training block.

However, when I add :


if &counterError > 14
   bitmap instructionsBis1
   delay 20000
   message instructionsBis2
   bitmap instructionsBis3
   delay 20000
   message instructionsBis4
   bitmap instructionsBis5
   delay 20000
   message instructionsBis6
   set &counterError 0
 fi

I have an error stating that I have an unknown statement (even though this bit of code works perfectly fine when tested in some "task" parts with other stimuli).

Is it impossible to put conditional statements in blocks or am I making a mistake ?

Thanks !
