Unable to select storage pool

[Yonny24]

Hi,
Just got to say these scripts are awesome! Thank you!
Now I'm trying a plex container but having a daft issue trying to select the storage pool. No matter what I type on the keyboard nothing will select the pool I want. tried 'x' 'y' every character but nothing appears on the parenthesis.
How do I select the pool to continue on OK? (maybe a very simple answer)

tab = move
space bar = select
