on 1:TEXT:*:*hello*:#:{ echo -s hellows }
See that extra *: you have in there? Remove it and it will work.
on 1:TEXT:*hello*:#:{ echo -s hellows }
Why did everyone reformat what was asked for? ($1 == Hello) is not the same as :*hello*:, though (*hello* iswm $1-) or (hello isin $1-) would be. MaGoNeGrO only wanted to echo to status the word hellows, presumably to test it, if the word hello appeared anywhere on the line, (leaving aside the mistaken copy/paste described above).
