hi i tried the code below as well as empty and isset and it seems that even
if the variables that have valid data in them they also get excluded from
display with the empty ones.. does "" mean any string? or is it the normal
empty string?
i need to know if the vars that dont get filled in from the form are empty
or not... and this isnt working very will...
any idea why this happens?
ps if i put & or && between if statements it gives me a parse error...
