[OpenLayers-Users] Javascript - Functioncall: strange behaviour

[Marc Jansen]

Hi Harry,

just guessing, but does IE show anything when you set the options-value 
as well as its text? Try to add

sbox.options[x].value=streetlist.features[x].properties.Adresse;

after

sbox.options[x].text=streetlist.features[x].properties.Adresse;

As I said, this just a guess.

Regards,
Marc
