'map is undefined' error in firefox

Hi,

I'm new in coding world. I may be diong a silly mistake. I developed
an API which geocodes UK postcode and displays in UK marker with an
info window whn the mouse hovers over the marker. It works fine in IE
but gives an error 'map is undefined' in firefox for the first time.
However when I refresh the firefox page I could see the markers
showing. Heres my test link http://doteditor.wateraid.org/temp/temp786.asp?.
Below is the code. I'm very close but confused which part is wrong.
Can you help looking below code what has gone wrong with firefox being
nasty giving errors?
