Save and Load in the build

I've had a lot of conversations and a lot of no progress. Everyone has been really helpful and their advice has helped tweak a few other things that were wrong but were not the problem I was trying to resolve.

I am using binary formatter for my method of save and load.

I have 3 source codes that have their own save and load. As long as I'm in the editor, everything works great. Once I create the build it no longer works on 2 of the 3. There is nothing different between the three save and loads except for what they save and load.

I have tried changing the write permissions in the player settings, I have tried changing where I place the location of the save load functions, nothing.

What would cause these 2 codes to work perfectly in the editor and then not be properly called once i place it on an adroid.
