Issue with combining ingredients in Calorimetry

In the lab I’m currently working on, I’m instructed to go to the stockroom in Calorimetry and obtain: the coffee cup calorimeter, the 1 M HCl solution, and the solid NaOH by placing all 3 items on the front shelf. Every time I grab either the HCl or NaOH, it blocks out every other ingredient and I’m not able to grab anything else. Is there something I’m doing wrong?

@Tapey I’m sorry you were struggling!
Yes, when you grab the HCl or NaOH it will gray out every other item from the shelves that are not allowable combinations. But you can definitely still select the HCl and the solid NaOH that are paired together on the shelf!!
