Forum:Fields and MST

Lets say my opponent has a Field Spell Active. I activate my own field spell but he use MST or Dust Tornado on is activation and destoys it.

When i activate my own Field Spell card, the opponent's active Field Spell is destroyed when mine resolves and becomes active on the field, due to the one active Field Spell card rule.

While chaining MST/Dust to a Field Spell card does not 'negate' but, there is no time when there are two active Field Spell cards, therefore my opponent's will not be destroyed. Im right?

So, if my opponent have a Necrovalley and I activate a Geartown then he chains MST/Dust, I get the trigger eff of Geartown?

And if i activate Geartown and he chains MST/Dust I dnt get it?

Finally (if im right), why MST/Dust can stop the "Activation" if there are a Field, but cannot if there are not.
