Check box based on value of another field

I have a checkbox that I want checked when the value is equal greater than 2500 and unchecked when below.  Trying to run a validation script but I can't figure out why this isn't working.

if (event.value >= 2500)
{
this.getField("PriceBox").value != "Off"

} else {
this.getField("PriceBox").value == "Off"
}

This will only work if the Export Value of the check-box is "Yes". To make it independent of that you can use this code:

 

this.getField("PriceBox").checkThisBox(0, (event.value >= 2500));

Your code is nearly correct, assuming it's a validation script on the text field where the number value is entered. 

the problem is that you are using comparison operators, instead of assignment operators. 

Here's the fix.

if (event.value >= 2500)
{
   this.getField("PriceBox").value = "Yes"
} else {
   this.getField("PriceBox").value = "Off"
}

    Try:

    // this is a field level calculation script that
    // goes in the AMOUNT FIELD
    // Assumes PriceBox is a yes or no checkbox field

    var amount = Number(this.getField("AMOUNT FIELD").value);
    var checkbox = this.getField("PriceBox");

    if (amount >= 2500) {
    checkbox.checkThisBox(0, true); // Check the box
    } else if (amount < 2500) {
    checkbox.checkThisBox(0, false); // Uncheck the box
    }

    event.value = amount; // Optional, if the field should still show the value
