!isset

[mlecho]

hi guys...not sure how to do this. I am testing to see if a variable has been passed using GET. If it isset, i would like php to echo one response, but if there is not variable (user shoots a blank form) then i would like php to echo something else. So far, i have been trying this:

if(isset($theseDays)){
echo ("&reply=".$personName." thanks for your submission.&");

}else {
echo("&reply= Invalid entry&");

}

but, that is not doing the job...how do you negate isset . I tried !isset, but as you pros know, that does not work...any ideas?

Might you be looking for this?

if (isset($_GET['theseDays'])) { 
    echo ("&reply=".$personName." thanks for your submission.&"); 
}else { 
    echo("&reply= Invalid entry&"); 
}
