changing the text in one of the options under the coro type

good day sir!



i would just like to ask on how can i change the text of one of the options in the coro drop down list. for example, i have this list (value: text):



1: bmw

2: mercedez benz

3: jaguar



then, i want to change ‘mercedez benz’ to ‘audi’.



how can i do that sir?

init
    var c= grid.getCombo(i);
    c.put(1,“bmw”);
    c.put(2,“mercedez benz”);
    c.put(3,“jaguar”);

change
    var c=grid.getCombo(i);
    c.remove(2);
    c.put(2,“audi”);
