Niels Emmen ( - Holandsko)

Potrebujem experta na tabuľky Google. Mám rôzne tabuľky, ktoré sa navzájom spájajú (myslím pomocou skriptov). Jednu z primárnych tabuliek potrebujem skopírovať a skontrolovať, či tam skript funguje. V súčasnosti to tak nie je. - Tabuľku je potrebné skopírovať - Skript musí fungovať na novej tabuľke - Skript musí byť zmenený v „starej“ tabuľke
