Problems with triggers from e-prime to Aquisition (URGENT)

Dear All,

the original transcript is:

question2.OnsetSignalEnabled = True
question2.OnsetSignalPort = &H378
question2.OnsetSignalEnabled= True
question2OffsetSignalPort = & H378

products2.OnsetSignalEnabled = True
products2.OnsetSignalPort = &H378
products2.OffsetSignalEnabled= True
products2OffsetSignalPort = & H378

question1.OnsetSignalEnabled = True
question1.OnsetSignalPort = &H378
question1.OffsetSignalEnabled= True
question1.OffsetSignalPort = & H378

products1.OnsetSignalEnabled = True
products1.OnsetSignalPort = &H378
products1.OffsetSignalEnabled= True
products1OffsetSignalPort = & H378

question1.OnsetSignalEnabled = True
question1.OnsetSignalPort = &H378
question1.OffsetSignalEnabled= True
question1.OffsetSignalPort = & H378

products3.OnsetSignalEnabled = True
products3.OnsetSignalPort = &H378
products3.OffsetSignalEnabled= True
products3.OffsetSignalPort = & H378

and runs well - the only problem is when I insert the Writeport after each 
condition. Then, the first command stops working! 

Thanks again!
