Javascript concatenating numbers, not adding up

Question

It keeps concatenating my numbers into 2111 instead of 5. Why is this? I\'ve tried using parseInt with no luck. res3 btw represents a query into my database that I\'m execut

Answer 1

you can parse your data according to desired type as follow

dt_total_hours += parseInt(res3.fieldByName(dt_cost_per_hour));

you can also use parseFloat method as well
