Millisecond Forums

I am trying to make a Cedrus RB 540 response pad work in my IAT script. It works fine when I run the XIDResponseTest script but I have yet to make my trials advance using the response pad in my own script. 

Here is what I am doing. 

<xid responsepad>
/ product = responsepad
</xid>


<trial attributeA1>
/ inputdevice = XID
/ isvalidresponse = [xid.responsepad.lasteventbutton == 3 || xid.responsepad.lasteventbutton == 5;]
/ correctresponse = [xid.responsepad.lasteventbutton == 3 && xid.rresponsepad.lastlatency<1000;]
/ stimulusframes = [1 = attributeA1, attributeA2]
/ posttrialpause = 250
</trial>

I copied the xid command off the online documentation but it keeps telling me that the brackets (  are wrong. If I change it to (  ) instead of [ ] the script will run, but button presses dont advance the trials. 

Im not sure what I am doing wrong. 
thanks
