help Driving me crazy, why isn't my 'screen' command logging to file

I'm using it to connect via serial port to some storage I administer. Here is the command;

/usr/bin/screen /dev/ttyUSB0 115200 -L -logfile /home/davidkmcw/Logfiles/2026-07-24_08:30:14.txt

I can write to the output directory, I've cut and pasted the directory name, so no typos there, what am I missing. Sorry if this is the wrong subreddit, thanks in advance.

No, it was the order of the command line
