WANUP Script

So this is likely something simple - but I'm unable to figure it out
My WANUP Scripts don't seem to work at all - they're running off a USB pendrive with entware on it...so my first guess was that probably the drive isn't mounted yet.
So I installed cron from entware and set up the script to run via cron - that just doesn't seem to work.
Script runs perfectly when executed from ssh shell...

Any ideas on what I'm missing?

Thanks for reading.
