Fishing Macro Help

[AllenWalker]

So I have made a good macro for forage which will make me stand, forage, automatically put whatever I forage in my inventory, then sit.
/stand
/doability 2
/pause 5
/autoinventory
/sit

I can't figure out how to get my fishing one to work though. I have tried a lot of different pause amounts with no luck.
this does NOT work
/doability 6
/pause 30
/autoinventory
