Andar is basically saying "You are not giving us a precise enough description of what exactly you want the script to do." He probably picked 400 words as an arbitrary "If you give us too short of a description, it won't be accurate enough for us to help you." threshold.
If you were to hire a script designer, s/he would need a detailed description saying what features the script had to have, how they needed to behave, exactly what you are trying to accomplish and so on.
It seems like you listed part of what you want the script to accomplish in one post, then part of what you want in a different post. It would make me wonder "What other requirements are inside this person's head but not yet posted?" Write up a detailed post where you clearly list what you want the script to do, exactly what game mechanics you need it to support, how the mechanics behave.
It should be so complete that someone should be able to look at it, make a script (or series of scripts), and they should exactly meet your needs, without need for any further question/answer sessions.
Until you do, it's not very likely people will want to make best guesses which you then say "Well, that's good but I need it to do XYZ as well."
It would be like saying "I want to hire you as an architect." "OK, what do you need?" "A house." "OK (shows plans)" "No, I need 2 bathrooms." "OK (shows updated plans)" "The bathrooms need to have room for a Jacuzzi tub." Eventually, the plans would be what you need, but it's far more efficient if the same exchange went like this:
You'd say "I need a house with 2 bathrooms, each with room for a Jacuzzi tub, a furnished basement which is 14x7, four bedrooms, two with a view of the ocean to the south, and a living room with a marble fireplace." With that one, detailed set of requirements, the architect has a much higher chance of making what you need.
