Counterbalance stimuli using conditional statements?

Hi,

I am trying to make a script that has a lot of counterbalancing, because ofthis I need the locations of the various distractor stimuli to be dependent onthe trial type. I've been trying to do this with conditional statements butcan't get it to work. I've copied the relevant bits of script below (hopefully that's enough - I haven't changed the rest of the script yet so thought it would be more confusing to attach the whole thing). I'm trying to test it just on the h position of filler 1 but I would want to change v position too later. Any help/ suggestions of how else I could do this would be appreciated!

<text filler1>
/ items = ("H", "Z", "o", "M","K", "o")
/ fontstyle = ("Arial Black", expressions.letterfontsize, false,false, false, false)
/ txcolor = black
/ select =sequence
/ txbgcolor = darkgrey
/ hposition = [
if (trialcode=trial.lowX1)values.hp2 else if(trialcode=trial.lowX2)values.hp3 else if (trialcode=trial.lowX3)values.hp4else if (trialcode=trial.lowX4)values.hp5
]
/ vposition = 1px * (display.canvasheight/2) - (values.p1distance/2) * expressions.ratio_pxpermm
</text>

/hp1 = 50%

/hp2 = 1px *(display.canvaswidth/2) + (values.p23horizontal/2) * expressions.ratio_pxpermm

/hp3 = 1px *(display.canvaswidth/2) + (values.p23horizontal/2) * expressions.ratio_pxpermm

/hp4 = 50%

/hp5 = 1px *(display.canvaswidth/2) - (values.p56horizontal/2) * expressions.ratio_pxpermm

/hp6 = 1px *(display.canvaswidth/2) - (values.p56horizontal/2) * expressions.ratio_pxpermm

/vp1 = 1px * (display.canvasheight/2)- (values.p1distance/2) * expressions.ratio_pxpermm

/vp2 = 1px *(display.canvasheight/2) + (values.p26vertical/2) * expressions.ratio_pxpermm

/vp3 = 1px *(display.canvasheight/2) - (values.p35vertical/2) * expressions.ratio_pxpermm

/vp4 = 1px *(display.canvasheight/2) + (values.p4distance/2) * expressions.ratio_pxpermm

/vp5 = 1px *(display.canvasheight/2) - (values.p35vertical/2) * expressions.ratio_pxpermm

/vp6 = 1px *(display.canvasheight/2) + (values.p26vertical/2) * expressions.ratio_pxpermm

</values>

/ ontrialbegin =[trial.lowX1.insertstimulustime(list.distractorXl1.nextvalue,500);]

/ ontrialbegin =[values.distractor = list.distractorXl1.currentvalue;]

/ ontrialbegin = [

if(contains(list.distractorXl1.currentvalue, "X")) values.category ="congruent";

else if(contains(list.distractorXl1.currentvalue, "N")) values.category ="incongruent";

]

/ ontrialend =[trial.lowX1.resetstimulusframes(); ]

/ stimulustimes = [1=fixation;500=sequence (fixationcover, XLD1, filler1, filler2, filler3, filler4,filler5); 600=sequence (eraser1, eraser2, eraser3, eraser4, eraser5, eraser6)]

/ validresponse = ("J","I")

/ correctresponse =("J")

/ response = timeout(2000)

/ beginresponsetime = 500

</trial>

Thanks!
