I found out what the problem is..
it is the last part..
ie.link(:text, "Next").click.. in the last web page, although "Next"
text is contained, link is not present since it is the last page..
Is there anyway, I can control "ie.link(:text, "Next").click" by
checking the presence of link beforehand?? so if link is present, then
proceed, otherwise.. halt.. I think my code will do as I wish once
this gets done..
thanks.
