MATLAB Subscript indices must either be real positive integers or logicals

Question

I do not know what's wrong with the code. Here's the snippet.

function popFreqResp_Callback(hObject, eventdata, handles)
list=get(handles.popFreqResp,'String');
str=list{get(handles.popFreqResp,'Value')};
if ((str == 'Stop Band')|(str == 'Band Pass') == 1)
    set(handles.edtCutoff2,'Visible') = 'on';
    set(handles.txtRange,'Visible') = 'on';
else
    set(handles.edtCutoff2,'Visible') = 'off';
    set(handles.txtRange,'Visible') = 'off';
end

You have to use it like that:

set(handles.edtCutoff2,'Visible', 'on');
