unwanted pixel effect on animated gif

[ProgramError]

Hi all,

I hope someone still looks at this forum who can help. I am using after effects 7 and wanted to produce an animated gif for inserting onto a web page.
I managed to export the composition but an unwanted grid appears on the exported footage when dither is select. I also tried exporting without dither selected but the result seems to be posterised. See links.
Can anyone advise?
