@Daniel_Grubbs Hey, Daniel: wondering if you could help with this. I’m creating a Powerball probability activity in which the students calculate the expected value of a ticket. On my screen #10, I can’t get the values from column 2 to multiply by column 3 and populate in column 4. Can you help with this slide?

You can’t just evaluate directly, unfortunately - you need to use `numericValue` or similar.

For example,

```auto
exV1 = numericValue(`${this.cellContent(1,2)}*${this.cellContent(1,3)}`)

```

(you also see I’ve wrapped the variables in ${ }, otherwise it won’t recognise them).

Finally, for the cellContent itself, you have to also wrap this in a string/latex too:

```auto
cellContent(1,4): "${exV1}"

```

All should work correctly with those changes.

Works great now. Thanks so much!
