user parameter script fails zabbix_get

[bambin0]

when I run from bash:
df -k / | awk '{print $5}' | grep -v Use | sed 's/%//'
everything always seems to work just fine.
however when I do a:
../bin/zabbix_get -s 127.0.0.1 -k freespace.root
I get a:
/dev/sda2 40313996 1191340 37074772 4 /

My file looks like this:
UserParameter=freespace.root,df -k / | awk '{print $5}' | grep -v Use | sed 's/%//'

Any help would be appreciated. Cheers.

Raplace 'print $5' by 'print $ 5'.

Thank you very much. That worked well.
