Using branched logic with slider response

In my experiment, participant move the slider to a new location. If they move the slider to the correct location, they will see the ‘correct’ routine, and if they move the slider to the wrong location, they will see the ‘incorrect’ routine. Currently, I am using the code shown in the image which shows a correct routine if the markerPos is equal to the correct location (loaded from an excel sheet using a text component). However, each time I run the experiment, the incorrect routine is shown even when the slider.markerPos is moved to the right location. This makes me wonder if I need to change slider.markerPos to another variable or if the answers in from the excel file need to be written in a different format. Right now the correct answer is loaded as (x,y) which is how I believe the slider.markerPos is read as.
