Hi,
I have a problem with a script that was running on Inquisit 5.
In my block, I define the value of an expression (condition):
<block conditioning_repeat>
/ preinstructions = (instru_conditioning_repeat)
/ onblockbegin = [ expressions.condition = "repeat" ]
/ trials = [    1-2     =     noreplacenorepeat(    training_1_positive, training_2_negative);
                3-22     =     noreplacenorepeat(    A_positive, B_positive,
                                                D_negative, E_negative, );        ]
/ screencolor = grey
</block>

In my trial, I define a branch depending of this expression's value :
<trial A_positive>
/ stimulustimes=[    0    =    amorce; 500 =A ; 2000 = eraser,    Pos1 ]
/ timeout = parameters.trial_duration
/ branch = [ if (expressions.condition == "repeat") trial.repeat ]
/ branch = [ if (expressions.condition == "think") trial.think ]
/ branch = [ if (expressions.condition == "control") trial.control ]
/ branch = [ if (expressions.condition == "control_time") trial.control_time ]
</trial>

However, the branch do not work anymore.
Any idea ? (script attached)
