How to save user input as variable I can compare?

I am trying to generate by Linear regression to get value a, then I want to get user input value b. So I can then take value a and b and plot them on a curve. But my user input is not storing values?

% Linear regression model: y ~ 1 + x1, calculate R^2 values for each ingredient

Mdl1=LinearModel.fit(SortedData_Cement(:,1),SortedData_Cement(:,9));

R^2_Cement = Mdl1.Rsquared.Ordinary;

Mdl1=LinearModel.fit(SortedData_Blastfurn(:,2),SortedData_Blastfurn(:,9));

R^2_Blastfurn = Mdl1.Rsquared.Ordinary;

% Prompt user to input a value for R^2 for all ingredients, accepting or rejecting value within a range. Display message to user.

exit=false;

msg='Please enter an R^2 value for Cement:';

while ~exit

data = str2double( inputdlg(msg) );

exit = (0<= data && 1>=data);

if ~exit

msg = 'Input must be between the values 0-1. Please re-enter: ';

end

end

exit=false;

msg='Please enter an R^2 value for Blast Furnace:';

while ~exit

data = str2double( inputdlg(msg) );

exit = (0<= data && 1>=data);

if ~exit

msg = 'Input must be between the values 0-1. Please re-enter: ';

end

end

The ‘data’ values are geing read correctly, however the second ‘data’ assignment is overwriting the first one.

Perhaps:

data(1) = str2double( inputdlg(msg) );

and:

data(2) = str2double( inputdlg(msg) );

with appropriate references to each of them in the test comparisons would work. (I subscripted them here, although anything that makes them different would work.)

Of course, thank you for your time!
