# script funkar i ie men inte i ff

## #1 — ket, 2006-02-26T09:43Z

Hej har problem med ett scrollbarscript. Det funkar perfekt i ie, men det går inte i ff, när jag använder doctypedeklaration. Tar jag bort doctypen funkar det i ff med.
Får detta felmeddelande när jag kör javascript-konsol via ff:
Fel vid tolkningen av värdet för egenskapen "top". Ignorerad deklaration.

Tack på förhand för ev. hjälp.
Mvh
Ket
