Hi,

just a quick question: if I set up an expression that includes a rand(x,y) function, will the random number be picked once or will it be repicked every time the expression is called? So for example:

<expressions>
/ MyExpression = 100 + rand(-50,50)
</expressions>

<trial Tester>
/ stimulustimes = [0 = TestText]
/ validresponse = (" ")
</trial>

<text TestText>
/ items = ("Showing number <%expressions.MyExpression%>")
</text>

If trial.Tester is repeated, will there be different values for MyExpression shown? If not, are there any circumstances that might cause the expression to draw a new random number? I'm asking because the closest analogues, new elements from lists, appear to be accessed only when called via a reference to list.MyList.nextitem in an ontrialbegin/ontrialend/branch, not when referenced in a text object using <%list.MyList.nextitem%> - or at least that was my understanding.

Thanks for any help!
