Help with syntax error

[adzoyi]

Hi! 

  I am writing a simple code and I get this error. The problem is,  "DON'T KNOW'. How do I code it right.

 "DON'T KNOW"

[ballardw]

Or old school:

'DON''T KNOW'

That is two single quotes in the middle. Useful to know as sometimes you can get values with mixed quotes and the single outside double quote won't do as expected.

"Some string that has height measures like 5' 6" in the middle."

Neither single quote works. You could use

"Some string that has height measures like 5' 6"" in the middle."
