                        clearvars SD to_plot
                    end
                end
            
            end % group
        
            % legende
            legend(ha(9),[p,q],[strjoin([test(1,2),'_',test(1,3)]), strjoin([test(1,2),'_',test(2,3)]), strjoin([test(2,2),'_',test(1,3)]), strjoin([test(2,2),'_',test(2,3)])],...
                'Location','southeast','Orientation','horizontal','FontSize',5.5,'NumColumns',1);

it is a pre-existing script, which I tried to change so that the output plot consists 4 means mit std. I want to have them 4 different colors. The original only consisted of the p(tsk) = plot(..) without any if/else argument. Now I added an variable COLOR2 with two extra colors and this if/else but it never enters the elseif and misses the variable q in the legend function. I know it's a pretty long code, but maybe someone can help.

Cheers Marcel

end % group

No, that is incorrect. You have for moNr, within for jo, within for tsk, so that "end" is matching tsk. You do the legend() at that point assuming that p and q have both been assigned to. But q is assigned to when grp changes. Your call to legend is within for sde which is within for grp so it will be a while before you see a change in grp.
