Error using subsref Index exceeds matrix dimensions

Question

I'm querying a database for license plate numbers. When the license plate is correct everything works great, but if the license plate is not in database, I get an error.

conn = database('baze', 'root', 'root', 'Vendor', 'MYSQL', 'Server', 'localhost', 'PortNumber', 3306);
setdbprefs('datareturnformat','structure');
sqlquery = ['select vardas, pavarde, laipsnis, pareigos, telefonas, marke, numeris, tarnyba, nuotrauka from info '...
       'where numeris = ' '''' word '''']; 
curs = exec(conn, sqlquery);
setdbprefs('DataReturnFormat','cellarray');
curs = fetch(curs);
numeris = curs.data{7}; %Error thrown by this line
if strcmp(word, curs.data{7})
    set(handles.text13,'foregroundcolor','green');
    set(handles.text13,'string','ENTRY');
else
    set(handles.text13,'foregroundcolor','red');
    set(handles.text13,'string','DO NOT ENTRY');
end
close(curs);
close(conn);

It looks like i don't have 7 cells in my cell array. I don't know how fix this.
