Hi, I am searching datas from 2D array but sometimes my vi cant found or calling wrong data from my table. I need found my input (or closest value) and use this data for calculate other paramethers. 

My search sub.vi, my main.vi Screen Shot(ss.png) and my datas in attachmets. Another problem is how can i call perfect this datas to my main.vi?

Thank you.

You can do something like this to find the values read from the file is within a specified limit. This is just to get you started, modify according to your requirement.

Your taktic is working for when i search a data from first cloumn then i can match with 2.nd cloumn.

But when i try search data in 2.nd cloumn i cant match true value from first cloumn. 

How can i fix this?
