fix n/a thinkscript options volume urgent work....

first of all I need that code to be completed for the volume of the puts. Second, I need the entire script to be able to read the futures and/or index options market. And thirdly, I would like to add to the total sum of that range that I have available to the script. that calculates the total sum of all the volume of calls, and total volume of puts, of the entire range.It seems reasonable to me. Another condition that I would like to put on the script is exactly the same but for open interest
