How to properly import excel data, insert values through "EDIT FIELD" and run a function using App Designer in Matlab?

Hi everybody!
I'm trying to create a GUI that open an .xlsx file, importing the table as a matrix called "data". Then I want to manually insert values by "Edit field (numeric)". These values should be matrixes, called: SM, SRT, beta, LAT. Once I have uploaded all these matrixes I want to run the main function using the button RUN. The problem is that I don't see anything uploading as matrixes, so the function gives me the error " NOT ENOUGHT INPUT ARGUMENTS".
Any helps?
THANKS IN ADVANCE :) !!

What is this
output = thorntwMater()
You have nothing as the input arguements so that's the error it's going to throw.

@Cameron B thank you for your reply. Yes, i tried to insert the input variables, which are the ones created before: SM, LAT, SRT, beta, data. I get this error: Undefined function or variable 'data'. It seems MATLAB doesn't recognised the variable data, which is extracted by the excel file in this way:
function load_dataPushed(app, event)
[file, path] = uigetfile('*.xlsx');
data = readtable(fullfile(path, file));
app.UITable.Data = data;
app.UITable.ColumnName = data.Properties.VariableNames;
end

Just so we're clear - what you're saying is that when you click the RUN button, it gives the error right? If so, that means whatever the function attached to the RUNButtonPushed callback is what is giving you trouble. That means that this
output = thorntwMater()
is not correct. Can you post whatever function thorntwMater() is so we can figure out what the inputs need to be? Or can you at least tell us what the inputs to the function are? We can't help you without that information.
