Increase a variable in Dynamic Text field with JS

Hi there,

I got a button on the stage and a variable set to 0.

I would like to increase the value of the variable every time the user clicks on the button.

I try this code but not sure about the function...

//dtc_Hits is the instance name of the dynamic text field;

//inst_ButtonMovie is the instance name of the button to be clicked

var Hits = 0;

this.dtc_Hits.text = Hits

this.inst_ButtonMovie.on("click", function(increaseHits) {

Hits++;

})

PS. I know that the error is in the line Hits++ because I try an alert message and it works...
