Very hard to understand what you're saying... Try to just say it in Spanish and I'll use Google Translate on my side.
Also why did you remove all the parentheses? o_o
Not using them is the legacy syntax and is deprecated.
And if you do remove them you can't omit the space and do things like
input.@input;
And you can't just turn a mesf() into a mes(), there's extra parameters
Do you happen to be using rAthena and not using the right forums? I can't think of any other reason why you would turn a properly formatted script back to a horror show otherwise.
If what you want is to prevent the quest from being done again I had already added in the script a method to prevent it, just uncomment the line:
.quest_tratoa = 2;
If what you're saying is you can't get it to work at all, well in your modified version there is a ton of malformed lines, so fix that first.
