Google Apps Script - Variable Passed Between Functions Shows Up as Undefined - google-apps-script

Question

I have some code where there are some if/else if statements to determine the reason that a Google Form has closed. I want to pass this reason to another function which will send an email notifying me that the form has closed and the why. I don't know why the reason, which should be a string, is not getting passed to the function that sends the email.
I'm not dealing with the form at all in this code. For simplicity, I opened a new standalone script, not linked to any Google Form or Sheet, to test just this portion (determine reason and send email). Here is the code:
First function to determine reason the form closed and to call second function to send email:
function FindReason() {
var Day1Seats = 5;
var Day2Seats = 5;
var Day1Responses = 6;
var Day2Responses = 1;
var FormClose = false;
if(Day1Responses >= Day1Seats) {
var reason = "All seats taken for Day 1";
SendAnEmail(reason);
}
else if(Day2Responses >= Day2Seats) {
var reason = "All seats taken for Day 2";
SendAnEmail(reason);
}
else if(FormClose) {
var reason = "Form close date";
SendAnEmail(reason);
}
}
Second function, which sends email (email address obviously changed for privacy):
function SendAnEmail(closereason) {
var recipientTO = "name#example.com";
var subject = "This is the subject";
//var closereason = "All seats taken for Day 1";
MailApp.sendEmail({
to: recipientTO,
subject: subject,
htmlBody: (new Date()) + "<br>Your form has been closed because: <br>" + closereason + "<br>End of message."
});
}
When I run FindReason(), I do get an email but the body doesn't properly show the reason. This is an example of the emails I get:
Sun Feb 24 2019 12:26:01 GMT-0800 (PST)
Your form has been closed because:
undefined
End of message.
I don't know why the reason is shown as undefined. I tried setting the reason inside the SendAnEmail function (the line that has been commented out) and that worked properly, but I need to be able to change the reason.
Edit: It works now. It turns out the "run" button was set to run the "SendAnEmail" function rather than the "FindReason" function. Thanks to everyone who offered suggestions.

Answer 1

What's probably happening is that else if(FormClose = TRUE) is not going to work.
= is the assignment operator, you want equality, which is ===.
TRUE is lowercase in js, so you want true.
You also use False, which should be false.
If you look in the google scripts editor's console, you should see an error of some sort, because it won't know what False or TRUE are (it will think they are undeclared variables).
try else if(FormClose === true) or even more simply, else if (FormClose), because if it evaluates to true, that will do the job.
function FindReason() {
var Day1Seats = 5;
var Day2Seats = 5;
var Day1Responses = 6;
var Day2Responses = 1;
var FormClose = false;
if(Day1Responses >= Day1Seats) {
var reason = "All seats taken for Day 1";
SendAnEmail(reason);
} else if(Day2Responses >= Day2Seats) {
var reason = "All seats taken for Day 2";
SendAnEmail(reason);
} else if(FormClose) {
var reason = "Form close date";
SendAnEmail(reason);
}
}
