(compiling appinventor/ai_nomfundofakude965/MASISIZANEAPP/Screen6.yail to appinventor.ai_nomfundofakude965.MASISIZANEAPP.Screen6)

ERROR: appinventor/ai_nomfundofakude965/MASISIZANEAPP/Screen6.yail line 144: duplicate declaration of 'back'

ERROR: appinventor/ai_nomfundofakude965/MASISIZANEAPP/Screen6.yail line 144: (this is the previous declaration of 'back')

Kawa compile time: 21.03 seconds

In the Designer, rename all 'back' buttons to 'btnBack' to avoid a bug in AI2.

P.S. Could you export an .aia of your app (before fixing it) and try to Build it on the server

It would be a good test of whether or not that bug has been fixed.

Unfortunately it hasn't
