Thanks a lot, Dave!
Especially for the correct examples that you've posted before in this tread,
they will save me some time.

I stand corrected. The functions reference does indeed give that flawed example, which I had overlooked at first. Thanks for pointing this out -- I will make sure the example gets replaced with a valid one.

Yes, I am well aware of the functions reference. However, I don't think any example gives the use case you are alleging in the /position attribute: "Inquisit documentation gives a following example of using replace() function to get randomized picture position:
<picture mypic> / items = ("foo.jpg") / position = (replace(0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100), replace(0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100)) </picture>"
I have posted valid examples in my previous response.

By documentation I mean the full documentation of inquisit objects, otherwise known as help. :) You can find it under: Help --> Table of contents
then in the table of contents: Language Reference --> Expressions --> Functions
And then under selection functions there are examples where
this way of using replace() is presented.

To clarify, the correct way to do this would be
<block myblock>
/ trials = [1-10=mytrial]
</block>
<trial mytrial>
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>
<text mytext>
/ items = ("A")
/ hposition = replace(25%, 75%)
/ vposition = replace(10%, 50%, 90%)
</text>
or alternatively
<block myblock>
/ trials = [1-10=mytrial]
</block>
<trial mytrial>
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>
<text mytext>
/ items = ("A")
/ position = (expressions.randpos, 40%)
</text>
<expressions>
/ randpos = replace(25%, 75%)
</expressions>
The syntax in your /position attribute(s) is in fact not valid, as far as I am aware.

Where does the documentation give those examples?

Hello Inquisitors!
I have a relatively simple problem but could not get my head around why my approach does not work.
Inquisit documentation gives a following example of using replace() function to get randomized picture position:
<picture mypic> / items = ("foo.jpg") / position = (replace(0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100), replace(0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100)) </picture>
In my experiment I use the same syntax: <picture negpic> / items = neg / position = (replace(15, 85), 50) </picture>
but it gives me following errors: Element: picture.negpic Attribute: position Message: Setting has invalid text ', 50)'.
Element: picture.negpic Attribute: Message: Expression 'replace(15,' is invalid. Unmatched parenthesis.
However, my parentheses are matched, I have also checked around
(before the definition of the picture and after) and everything seems to
be a legitimate Inquisit syntax. I have also tried using ';' instead of ',' or adding spaces - the error is the same.
Do you have any ideas why it might not work or what should be done to fix the problem?
