Field too small ???

hi, I have a field in my DB that supposed to display a hyperlinked google map to the location.
my field is setup as TEXT in mdb,

and HTML in the LIST page

edit as text area height 600,width 500
however when I paste the HTMl code I get erroro saying
field to small, try po paste less data
but this is the data I am posting:it is not big??isn't it?

it does dysplay while editing, but it is not saved.
