hi  
sorry, I’m new in Thunkable, if you refer a “version name” and “version code”, when in “version name are insert NaN” I don’t download; when I changed NaN in number 2, after 3 attempts the download is OK.  
which are correct insert code in that positions?  
thanks

the version code should count up by +1 every time you download. You should check before downloading if it says NaN.

it should always count up, and it should never display NaN
