"Code took too long to run" is the euphemistic version of "This code is in an infinite loop."

When you wrote "count + 1;" it adds 1 to the count, but it doesn't store that computed result anywhere. To increment the count, you could use the addition assignment operator: "count += 1;"

Hey! If you want to change or add to the contents of a variable you need to use the "=" sign. Meaning that the code should go something like this:

count  = count  + 1;

And in your case, if you want to use the shortened version, then you can write it out like this:

count += 1;

So you're just missing the "=" sign in order for the code to work ;)

Hope this helps & good luck!
