Some quick php help needed

[chrisnrach17]

I have a contact form in php format. The results are e-mailed to me.

I'm having a problem getting an indication of whther the Subscribe field is checked or not checked. The other fields (text fields) come through fine.

Can anyone suggest what I need to put on the Subscribe line to tell me if the checkbox has been checked or not?

$message = " $todayis [EST] \n
Attention: $attn \n
Message: $notes \n
From: $visitor ($visitormail)\n
Postal Address: $postal \n
Subscribe: $subscribe \n
Additional Info : IP = $ip \n
Browser Info: $httpagent \n
Referral : $httpref \n


thanks in advance if you can help on this!
