I’m in need of some help on slide 7 of [this activity](https://teacher.desmos.com/activitybuilder/custom/619d89777cd6809e4ae79577).  
When the kids type in the 2nd inequality x+5y≥2000, it graphs a dashed line instead of solid. I’ve tried to add a similar code to the CL as what the math1 input has, but when I add this:

number(`s_{trict}`): when parseInequality(math2.latex).isStrict 1 otherwise 0

It gives me a duplicate definition error. This is a newer skill for me, so I’m not quite sure what the `s_{trict}` is doing, but I have a feeling that something needs a different name there?

Any help would be much appreciated!

If you used the exact same code for your second number s\_trict, there’s the conflict. You just need a unique name for the number (e.g. s\_trictg)

That fixed it! Thank you so much!
