should I use count to see if button was pressed?

[wolfing1]

So far I've been using instructions like 'if request.form("var.x") <>
"" then ...' but then I found that if images are disabled (or not
found) and I click on the alt text, then Firefox (or was it IE?) sends
a 'var.x=' in the response so my instruction doesn't detect that the
'button' was pressed. Is it safe to change my checks to 'if
request.form("var.x").count 0 then ...' instead? does it work for
all browser responses and HTML standards, etc?

By 'button' I mean <input type='image' sorry
