NaN appearing when I insert a variable

ChocoChoco

So, when I was doing a story, I set a variable like this:

<<set $Knowledge to $Knowledge += 1>>

But when I wrote $Knowledge, it comes out as NaN. Literally says NaN! Why?

I don't do Sugarcube 2, as I use the online version. Thanks.

This is what it looks like:

<<set $Knowledge to $Knowledge += 1>>

You now have $Knowledge!

You're not initialising $Knowledge. "+= 1" adds 1 to the existing value of Knowledge, so you're trying to add it to a variable that does not exist.

In your StoryInit passage, place <<set $Knowledge to 0>>

You want to do this for every variable.

Thanks! I think I have missed that. I'm the forgetful sort, heh. Thanks for taking the time to answer my stupid and obvious question.

To be specific, Claretta meant that you should initialize your $variables, not necessarily set them all to 0.
