Snažím sa pridať 2 výstupy spolu a zobraziť ich výsledok v tretej/štvrtej displeji sa na 7-segmentové displeja. Každý výstup je uvedené v ich vlastných segment, resp. Štvrtý displej je dvojciferný počet (Max je 14, Min, že 0). Dostávam chybové hlásenie, že musím napísať všetky inštancie prípade "pridať". Nie ste istí, kam stadial. Každá pomoc je vítané.
