Let me start this off saying that I'm not very familair with MATLAB. I'm a first year engineering student working on a final project and I might have decided to try a project a tad out of my lead. So please specific with your advice. With that said, here's my problem:

I have a total of 5 figures (GUI's) with pushbuttons. Under the pushbuttons function I have written:

global Variable_One 
Variable_One={1 'Name'};
close

Then, in my script, I assign Variable_One to my workspace by using:

openfig('Figure1','reuse');
uiwait(Figure1)
global Variable_One;

With my first two figures, this works perfectly. However when trying to do the same with the third figure later on in the script, Variable_Three is assigned to [] rather than {3 'Name'} .

So frustrating! I'm so close to finishing this project. Plese, all help appreciated thank you.

That would happen if your routine that defines Variable_Three is missing the

global Variable_Three

before the assignment.

Double-check that the global is present and that you have used the same variable name there -- for example that you do not accidentally have

global Variable_three

or

global Variable_Trhee

I triple checked everything. Every capital letter, underscore, etc. is in check. The code is identical to the working code earlier in the script (except for the variable names of course) That's why I'm so confused.

Could you add a disp() or a breakpoint to be sure the assignment is being reached? In case for example a different callback is being invoked than what you expect
