Problem sharing data between 2 apps in app designer

Hello everyone,

I have a problem with sharing data between 2 apps in the app designer. The first app is called "appPDDCP", and the second one is called "appPDDCP2". I have 4 variables in 4 diferent edit fields in the first app, so I declared them as global:

global Q

global B

global V

global h

Q = app.EditField_2.Value;

B = app.EditField_12.Value;

V = app.EditField_9.Value;

h = app.EditField_7.Value;

After that, I need to call those specific variables in the second app, so I'm trying it do it like this:

load(Q);

load(B);

load(V);

load(h);

Then, I need to make a math operation and to be placed in a specific editfield, like this:

app.EditField.Value = (162.6*Q*B*V)/(h);

I have no idea why it is not working, so please someone help me, how can I call a specific variable of a specific app to another app in the app designer?

Thank you so much for your attention.
