Hi All, I am new in app designer and I am trying to run a "2 steps" app. The first part calculates my outcomes (running fine) and the second part needs to use some of these outcomes to perfrom some further calculations. How can I save/pass/link the outcomes produced to be part of the second callback function?. I tried creating a structure whithin the first callback function, for example, app.var1 = outcome1, however doesnt work and gives the following error "unrecognized property 'var1'…". An y suggestions how to do it?
