Dumb script that won't work

[Googi]

NPC Code:

---

if (created) {

  setimg door.png;

  setshape 1,32,32;

  mine.onea=0;

}

if (playerchats&&strequals(#c,rent mine 1)&&playergralat<5&&mine.onea=0){

playergralat-=5;

tokenize #a;

mine.onea=1;

say2 You have mine 1 for 30 minutes;

timeout=1800;

}

if (playerchats&&strequals(#c,rent mine 1)&&mine.onea=1){

say2 That mine is rented already;

}

if (playerchats&&strequals(#c,rent mine 1)&&playergralat<5&&mine.onea=0){

say2 You need 5g to rent a mine!;

}

if (playertouchsme&&(#a,#t)&&mine.onea=1){

setlevel2 rentmine2.nw,6,7;

}

---

I keep getting the "this mine is already rented" message.
