error message undefined variable best_salt_2

I cant see that best_salt_2 hasnt got a value in this function I have attached; I get an error saying ''undefined variable best_salt_2''

Can somebody help me? :)

What input you have used to the function?

Hey there, The error you get is probably because you have not set the value i.e initialized variable best_salt_2 before trying to check something on it, for example performning isempty(best_salt_2) on an undefined variable will throw that error.

Can you screenshot the error line and your workspace at that point. I can explain it better then.

PS: try to intend the code so it is readable. It saves a lot of time in debugging.

@KSSV Hi This is the input that goes in from another function,

S={'NH4Cl'; 'MgCl2'; 'CaCl2'; 'KCl'; 'ZnSO4'; 'NaCl'; 'ZnBr2'; 'CH3CO2K';'HCOOK';'HCOONa'; 'CaBr2'};

str={'Choose salts available, minimum of two and maximum of three'};

result=listdlg('Promptstring',str, 'ListSize', [100,100], 'ListString', S, 'SelectionMode', 'multiple');
