Does not contain definition

Hi all, I’m currently creating a modified version of the Survival Shooter demo. I’ve added various elements including power-ups and lives but have run into an issue. I am trying to reference a public integer (lives) that I have created in another script. Lives resides in the ‘PlayerHealth’ script and I want the ‘LifePickup’ script to be able to increase this integer. However, when I try and reference the lives integer I am getting the message ‘Error CS0117: ‘PlayerHealth’ does not contain a definition for ‘lives’.’ I am able to reference other integers in the PlayerHealth script that are established in exactly the same way but not my lives integer. I’ve trawled the forums but can’t find any solution to this.
The first code snippet attached is two exerts from ‘PlayerHealth’, this demonstrates how I have set up all the variables. I can add in further code from this class if needed. The second is the ‘LifePickup’ script which is trying to reference the component. This is being done on the final line.
Any help that I can get would be really appreciated. Thanks!

namespace CompleteProject {

Your PlayerHealth class is defined inside this namespace.

In order to use it in your LifePickup class, you need to either, define the LifePickup class inside the same namespace, or add a “using CompleteProject” line at the top. (or reference everything using the full namespace path, eg. CompleteProject.PlayerHealth)

So, I’m surprised the compiler even get at far as the error you mentioned. I would have expected it to error-out on the declaration of the PlayerHealth member of LifePickup!

FYI: I don’t see any other issues that could cause this problem.
