How to make my upgrades menu work

[gamevice]

Hi all

i have a flash game that i am creating but the upgrades menu doesnt want to work, i have a text box that i use for my coding so that if the text box is showing a certain number something happens (I.E A function happens), but i cant seem to get this working here is my code:

time.onEnterFrame = function() {
if(_root.cash <= 99) {
_root.count = 1;
}
}

time.onEnterFrame = function() {
if(_root.cash >= 100) {
_root.count = 2;
}
}

time.onEnterFrame = function() {
if(_root.cash <= 149) {
_root.count = 3;
}
}

I am using A.S 2.0 on this and i have two text boxes working on this, the first the cash text box and this goes up every time the player kills an enemy, and the second text box is a the count text box which should go up when the cash equals a certain amount how can i get this to do it? please help

time.onEnterFrame = function () {
    if (_root.cash.text<=99) {
        _root.count.text = 1;
    }
    if (_root.cash.text>99 && _root.cash.text<=100) {
        _root.count.text = 2;
    }
    if (_root.cash.text>100 && _root.cash.text<=149) {
        _root.count.text = 3;
    }
};

That doesnt work? :S Nothing happens, when the text boxes reach a certain number they have to run a function how would you get that to work?

E.G

time.onEnterFrame = function () {
if (_root.cash<=99) {
math99;
}
};
