DB Field And Name Info

I am using :

<% FOR EACH field IN size_info.FIELDS
Response.write("<option value=''>" & replace(field.name, "asize", "") & "</option>")
NEXT%>

to loop the names of the fields in a DB, but I cannot get it so that is the value of the data in that field is lower than 5 it simply doesn't show, i thought i might be this

<% FOR EACH field IN size_info.FIELDS
if size_info.fields.name.value > 0 then
Response.write("<option value=''>" & replace(field.name, "asize", "") & "</option>")
end if
NEXT%>

but that doesn't work.
