Pulling data from a dialog box and putting the info into an if loop

Trying to pull my input and run it through an if loop any ideas?

defineinput= {'A#'};
answer = inputdlg('Error code','Error Code Identifier',[1 75],defineinput);
userin={answer}
if userin=='A1'
    disp('Engine Oil')
else
    disp('fault code not recognized')
end

1) no need to put the 'answer' result in another cell array (userin={answer})

2) use strcmp() or strcmpi() to compare strings instead of (userin=='A1')

3) There's no such thing as an 'if loop'. There are for-loops and while-loops and conditionals (if, else...)

defineinput= {'A#'};
answer = inputdlg('Error code','Error Code Identifier',[1 75],defineinput);

if strcmp(answer{:},'A1')  % use strcmpi() for case insensitivity
    disp('Engine Oil')
else
    disp('fault code not recognized')
end
