If this template helps then use it. If not then just delete and start from scratch.

**OS** (e.g. Mac):  
**PsychoPy version** (e.g. 2.3.x):  
**Standard Standalone? (y/n)** If not then what?:  
**What are you trying to achieve?:**  
I want to use participant’s rating in the first slider (prior belief) as a starting point in the second slider which measures posterior belief.  
**What did you try to make it work?:**  
First attempt: I used the “slider1.getRating()” variable or “$slider1.getRating()” in the starting value field of the slider component.  
Second attempt: I added a code component in the first slider and I created a variable slider1\_value =0 in the begin experiment (and begin routine) and I updated the value in the end routine slider1\_value = slider1.getRating. Then I used the slider1\_value variable in the starting value field of the slider component.  
**What specifically went wrong when you tried that?:**  
In both attempts, the marker was absent initially and appeared only after I clicked on the scale.

Hi there, here’s a demo that should do the trick. I’ve used `.startValue` to present the marker and place a fixation cross between the two routines to distinguish between the pre and post sliders

It works! Thanks a lot!  
I was not aware of the startValue function which is so useful.
