Error 1 occured at write to text file

[reek_l]

Hey there !

I tried writing a VI which takes some measurements at some particular time period, and then save it to a text file. But  I get  an error saying an input parameter is invalid at write to text file. This always happens during the second round of the loop. I've enclosed the screenshots.

Thanks in advance.

You close the file at the end of the loop and you never open it again.  Move the close file outside the loop (after it).

Thanks a lot Bill!

It finally worked.
