Switch between multiple functions MATLAB

Question

So I have an m. file script that contains 2 functions.
The first one (that's loaded when I run the script) and the second.
Each of them has a different GUI setup and different text in text boxes (sorry for tautology).

My program is about calculating stuff using economic formulas, and the final version of the program is going to have about 50 formulas in it. AND I don't want to make 50 separate scripts for each formula. What I want is to be able to switch between formulas inside one script.
So I made a specific push button for that purpose (code below) but when I press it nothing happens.

Can someone who's experienced enough tell me what did I do wrong? (I'm new to MATLAB).
Let me know if more information is needed, or the question is not clear enough. Thanks in advance!

Here's the whole script:

The one line you supplied us with looks fine! But what does the callback function (SecondScript) do? — Jens Boldsen

It loads entirely different program (calculator) with its unique interface and a dozen parameters to calculate. But it doesn't work! And what surprises me most, MATLAB doesn't display any error messages. — Johnnik

Did you try setting a breakpoint into SecondScript code and step in? Since the problem seems in this function, perhaps you might post it. — il_raffa

You still haven't posted the SecondScript-function, as I (as well as il_raffa) mentioned before the problem seems to be with that function. — Jens Boldsen

I have a trick, although i myself find it not very good-looking:

Assuming you put all of these functions inside a file myforms.m without any blank line. Then, at the beginning of your GUI, open and read your file:

f1 = fopen('myforms.m');
alllines = textscan(f1, '%s', 'Delimiter', '');
fclose(f1);

alllines{1} is now a cell array, and each element is one line from myforms.m.

Now, when you want to switch to a formula, you need to know the line number of its section in myforms.m, for example starting from line 10, ending at line 15.

Create a new file, i.e callme.m which should be called by your button, and write these lines to the file:

f2 = fopen('callme.m', 'w');
for i = 10:15
    fprintf(f2, '%s\n', alllines{1}{i});
end
fclose(f2);

Your callback function can then be @callme.

Thanks for the answer! But I don't understand what do you mean by "...at the beginning of your GUI..." I only have 2 m. files (myforms.m and callme.m). Are you talking about .fig file or some other matlab file extension I'm not yet aware of? This might sound stupid, but where exactly do I have to put this code you gave me?

I've put source and eventdata in a set of parentheses directly after the function's name and it solved the problem! I can now easily switch between formulas as fast as I can push the button.

Here's how my function's name looked like before:

function SecondScript

Here's how it looks now:

function SecondScript(source,eventdata)
