not a support question
Hey folkens
Jeg har købt gravity forms til 2 sider jeg er ved at sætte op. Men jeg er løbet ind i et problem med at GF ikke kan regne med decimaler, så jeg bliver nød til at indsætte en kode i min Functions.php.. Jeg har prøvet et par gange men hvergang kan vil siden ikke åbne bagefter og her sidste gang lavede jeg kage i det og nu er der en grå bar over min header.. har brug for hjælp til at få den kode in i min functions.php og bagefter fjerne den grå bar der nu er dukket..
