Example:
I have the below list in a single text file.
1234567,3456,apple,15.00
7654321,5432,ball,25.30
1237890,3789,car,35.67
How can I get all the details of a line record by just selecting any word from the line.
Example, if i input on a textbox “5432”, i will get “7654321”, “5432”, “ball”, “25.30”
thanks.
I tried to convert your work on my blocks, but ALL RECORDS are showing instead of just getting the row where my input is included.
here are my blocks
you are storing your text as csv table, i.e. each row does have the invisible end of line character \n
to get the blocks from @bodymindpower working, use the split block and split at \n (new line)

Who says that?
As you can see, in my example I separated the items with a space and my solution works. Of course you can also separate the items with \n (in rows) and then split at \n.
It looks the same to me …
what if
1234567,3456,apple,15.00
7654321,5432,ball,25.30
1237890,3789,car,35.67
is in a textfile, how can create a global variable from reading a textfile?
use the file component to read the textfile
