[RESOLVED] Dynamic variable in if statement treated as string?

Hello.
I have an array named theData and an object named myData which is generated from the array. I need my for loop to enable/disable buttons on the page depending on the value of the var dollars vs the value of myData.selectionName.cost

This is what I have so far

[CODE]
function setButtonState(){
for (var i = 0; i < theData.length; i++){
var selection = theData[i].name;
var nameCombo = selection + “Button”;
var costCombo = “myData.” + selection + “.cost”;
if (dollars < costCombo){
$(“#” + nameCombo).prop(“disabled”, true);
} else {
$(“#” + nameCombo).prop(“disabled”, false);
}
}
}
[/CODE]

The only part that doesn’t work is the if statement. Currently it checks dollars vs the string inside costCombo. I would like to compare dollars vs myData.selection.cost where selection is dynamic and set earlier in the function based on our theData[i].name.

How do I get the if statement to read costCombo as myData.example.cost instead of “myData.example.cost”

Also in #JavaScript _↴
