Pool address and port not in correct format error.

[Quantoxis]

I have entered my pool address and port separated by a colon as

set "POOL=eu1.ethermine.org:4444"
set "WALLET=0xaCc81B9f2196818f655F416c6568767A492c70e4.lolMinerWorker"	`

but when I try and launch mine_eth.bat it flags an error as

What am I doing wrong?
