I can not seem to figure out how to correctly input the codes. Every time I do a practice session myself, I only see x for each problem even when I entered the correct answer. I only get a check mark on slide 1

You shared student view and it is impossible to see the code.

Instead typing:  
`correct: input.numericValue =8`  
type  
`correct:this.numericValue=8`  
This will solve check problem. I do not know why this CL didn’t return error on `input.numericValue=8`  
it is probably that you have some variable named input in your activity.  
Hope this help.

Yup, this is the solution. I discovered `this` recently and it has made copying screens SO much easier. had to go in and replace all the input names everywhere. Ugh.

You can also set a variable in a component to a component name, so that you only need to change it once in that CL. For example, copying another table:

```auto
t=table24
cellContent(1,2): t.cellContent(1,2)
cellContent(2,2): t.cellContent(2,2)
etc..

```

Yup. Started doing that for modularity a few days ago, thanks!

Thank you so much! That fixed it
