"will not work" conveys no useful information. The code does something, what does it do?

Look at that statement very carefully comparing it to the syntax for [the analogRead() function](https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/) and [the if structure.](https://www.arduino.cc/reference/en/language/structure/control-structure/if/) Note, especially, the **placements of the parenthesis**.
