Thank you for your quick response ! 

Sorry, I tried to simplify the problem to be able to explain what I meant. 
I think your first solution might still work though.

The problem is that I want to use that value in many different stimulustimes with the value constantly being updated. 

Here's part of the script: 

<values>
/ prev_health = 4
/ prev_approach = 1
/ prev_good = 1
</values>

<trial cdt3trialmanvekpos_vek>
/ branch =[if(values.prev_approach==1 && values.prev_good==1) {trial.cdt3trialmanvekpos_vek1}if(values.prev_approach==0 && values.prev_good==1) {trial.cdt3trialmanvekpos_vek2}if(values.prev_approach==1 && values.prev_good==0) {trial.cdt3trialmanvekpos_vek3}if(values.prev_approach==0 && values.prev_good==0) {trial.cdt3trialmanvekpos_vek4}]
</trial>

<trial cdt3trialmanvekpos_vek1>
/ pretrialpause = 100
/ validkeys = (200,208)
/ stimulustimes = [0=man<% values.prev_health+1 %>_pos1, healthbar<% values.prev_health %>, hb, great1; 125 = man<% values.prev_health+1 %>_pos2, healthbar<% values.prev_health %>_1, hb, great1; 250= man<% values.prev_health+1 %>_pos1, healthbar<% values.prev_health %>_2, hb, great1;375= man<% values.prev_health+1 %>_pos2, healthbar<% values.prev_health+1 %>, hb, great1;500=man<% values.prev_health+1 %>_stand, healthbar<% values.prev_health+1 %>, hb; 750= man<% values.prev_health+1 %>_open1, healthbar<% values.prev_health+1 %>, hb; 1000= man<% values.prev_health+1 %>_open2, healthbar<% values.prev_health+1 %>, hb; 1250= man<% values.prev_health+1 %>_vekte, healthbar<% values.prev_health+1 %>, hb]

Note: this is only a small part of the trial elements that I have in the script (and of the stimuli).
So for that reason it would have been really easy to be able to use <% value %> but if it can't be done then I'll try to get it to work with the insertstimulustime attribute.

Thanks again,

Hi, 

I want to refer to values in the stimulustimes attribute, specifically, in the name of a certain variable.
However, referring to it via <%values.value %> as I would do in a text does not seem to work.

Is there any other way to refer to the value of a certain value ? 

For instance: 

<picture man1>
/ items = ("man1.jpg")
</picture>

<picture man2>
/ items = ("man2.jpg")
</picture>

<values>
/ valueA=1
</values>

<trial firsttrial>
/ stimulustimes = [0=man<% values.value1 %>] 
/ ontrialend = values.valueA1=2 ]
</trial>

You cannot use values like that. The way to do this is to use the <trial> element's insertstimulustime() function like so:

<trial firsttrial>
/ ontrialbegin = [if (values.valueA == 1) trial.firsttrial.insertstimulustime(picture.man1, 0); ]
/ ontrialbegin = [if (values.valueA == 2) trial.firsttrial.insertstimulustime(picture.man2, 0); ]
...
/ ontrialend = [trial.firsttrial.resetstimulusframes(); values.valueA += 1]
</trial>

However, why don't you simply use the value for item *selection* in a <picture> element, i.e.

<picture man>
/ items = manitems
/ select = values.valueA
</picture>

<item manitems>
/ 1 = "man1.jpg"
/ 2 = "man2.jpg"
</item>

with

<trial firsttrial>
/ stimulustimes = [0=man]
/ ontrialend = [values.valueA += 1]
...
</trial>
