Whats wrong with these two functions in my app?

hi

I am now attaching an app here , app3 , that includes 2 callback functions. I think there is something wrong in the first of them: function start analysis , it is a callback function. I have tried to find out but I dont understand why the app not continuing to the second choice led by error ==1. I ran my real program and got the expected results but with this app I am not doing so

The application property (error) that you are tyring to use is being created upon the start of the application, but you have failed to assign it a value anywhere within your code. Thus app.error is empty and will never be equal to 1 without a mechanism change its value.

@Allen Hi! So it doesnt help if I give a value to a error in a function that I am using in the app..?

[Muazma Ali]

what I am trying to say is that I gave it a value in a function that I used after the if statement.

Do I have to initialize it in th app.?

@Allen error is supposed to be an output value value from a function
