Hi Priya,
Is WT8000 comming from RT(result table)?
I guess no and because of this by reading it from RT (AMT=E 8000 means read WT8000 from RT) the amount will be 0.
Just DELETE first line you don't need it because your PCR is working based on WT8000
As you see it's like this * 8000) So you have AMT already and don't need to read it. By this line you will get it times to 2 (As you said in first post you are getting 2000 because AMT is 1000 and you are reading again and adding to the same WT.
