sorry, i don't get the basics ;-)
try to filter a list (in the sql field box) with this: <erzeuger_hersteller_dienstleister> = '<1>'
alias of field is "<erzeuger_hersteller_dienstleister> = '<1>'"
the field is a checkbox with only value 1.
0 users found, but there are a lot with this value ;-)
what i´m doing wrong?
thx
