Playerprefs not working right

[remote wharf]

I have a problem in a Unity project that im developing. I can't make the new values to be saved and used later at the same scene (it goes from this scene (shop) to another scene to then come back to the first scene (shop). Basically, I buy upgrades from a shop until it's "max", then, when I come back to this scene, the value is at level 1 (even though I already have the lvl max and I can't buy more because I have it at max lvl).

The images are all the code that I used. I've tried using playerprefs to save the new values, but it simply doesn't work. (I highlight the playerprefs code that I tried to use bit it didn't work).

If someone could help me it would be very nice, I have to finish this by next week 🥲😓.

I will send the pictures right in a moment

Do not send screenshots of code, specially not taken like that. It's unreadable. Send code like shown in the #📄・posting-guidelines

okok srry

This is my current code (i added the OnDestroy function and it still doesn't work):

Omg I didn't know that this format was possible 😮

There are some "//" parts in spanish, just for you to know

@remote wharf check if onDestroy function works first

[remote wharf]

It does I think

I'm not very good at this so I will ask basic questions

[blissful surge]

like check if you can even print something out in the destroy function

[remote wharf]

Like: debug.Log?

[blissful surge]

yeah

any updates?

I didn't have time, I'll let you know when I do
