okay here's problem have bunch of price ranges made using json object want dynamically change json object call in example:

json object:

and problem:

$("handler").click(function(){    $("#range").html(ranges.range_var.material_var.price)//i know extremly wrong }):

i trying substitute .range_var , .material_var for variables holding correct value change according user's choice?

you need use bracket notation:

ranges[range_var][material_var].price
