@andrewsimpson4 in the past i remember there was some prblem with numbers and text. To solve it definitly i decided to save always converting numbers to string, with tostring(), then when reading back to convert back to number, with tonumber(). Then i never had problems again. However, this might not be your problem here.

@Andrewsimpson4 Here’s an example of saving and displaying local data.


function setup()
    value=123
    saveLocalData("abc",value)
    value=3214
    saveLocalData("rty",value)
    value=653
    saveLocalData("xse",value)
    
    ld=listLocalData()
    for a,b in pairs(ld) do
        print(b,readLocalData(b))
    end
end

Many people here HATE Project Data, as it doesn’t get deleted with you’re project, local data is for Highscores, and Global data is something you want all(or a vast majority or two) of your projects to have access to.
For levels: do Project, For Highscores: do local

@CodeaNoob Local data doesn’t get deleted with the project either. Both local and project data could be a problem if you save a lot of data and then delete the project without deleting the data first.
