Two ints declared simultaneously, one "does not name a type"

Question

I have several integers, all of which are declared and set to zero in setup. However, in a method, I can only modify the value of half of those integers. The method is to read several buttons and return which of them have been pressed (precondition is that no more than one buttons are pressed):

 int readButtons(){
 rbuttonState = digitalRead(right);
 lbuttonState = digitalRead(left);
 sbuttonState = digitalRead(sel);
 obuttonState = digitalRead(off);
 nbuttonState = digitalRead(snooze);
 int ret = -1;
 if (rbuttonState != lastrButtonState){
 if (rbuttonState == HIGH) {
 ret = right;
 }
 }
 if (lbuttonState != lastlButtonState){
 if (lbuttonState == HIGH) {
 ret = left;
 }
 }
 if (sbuttonState != lastsButtonState){
 if (sbuttonState == HIGH) {
 ret = sel;
 }
 }
 if (obuttonState != lastoButtonState){
 if (obuttonState == HIGH) {
 ret = off;
 }
 }
 if (nbuttonState != lastnButtonState){
 if (nbuttonState == HIGH) {
 ret = snooze;
 }
 }
 }
 lastrButtonState = rbuttonState;
 lastlButtonState = lbuttonState;
 lastsButtonState = sbuttonState;
 lastoButtonState = obuttonState;
 lastnButtonState = nbuttonState;
 return ret;
}

Yet I have the errors that

Arduino: 1.6.12 (Mac OS X), Board: "Arduino Nano, ATmega328"
Nixie_Clock_0:65: error: 'lastrButtonState' does not name a type
 lastrButtonState = rbuttonState;

exit status 1
'lastrButtonState' does not name a type
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

(The last line of code is line 72). I am at a complete loss. Any help?

• Majenko: Where is the rest of your code?
• Mikael Patel: There is an end bracket too many. Indent the code correctly and you will find it.
• user3629249: the posted code does not contain 70 some lines of code. It only contains 40 lines of code. Post the actual code.
• Aditya J.: @Mikael Patel thanks! I can't believe I missed that!

Answer 1

the following code

1. is properly indented
2. is missing the declarations of the variables for the 'button states' and the 'prior button states'
3. has additional text about a format error
4. is properly indented
5. has the code blocks properly separated by a single blank line

and now the code

int readButtons()
{
 rbuttonState = digitalRead(right);
 lbuttonState = digitalRead(left);
 sbuttonState = digitalRead(sel);
 obuttonState = digitalRead(off);
 nbuttonState = digitalRead(snooze);
 int ret = -1;
 if (rbuttonState != lastrButtonState)
 {
 if (rbuttonState == HIGH)
 {
 ret = right;
 }
 }
 if (lbuttonState != lastlButtonState)
 {
 if (lbuttonState == HIGH)
 {
 ret = left;
 }
 }
 if (sbuttonState != lastsButtonState)
 {
 if (sbuttonState == HIGH)
 {
 ret = sel;
 }
 }
 if (obuttonState != lastoButtonState)
 {
 if (obuttonState == HIGH)
 {
 ret = off;
 }
 }
 if (nbuttonState != lastnButtonState)
 {
 if (nbuttonState == HIGH)
 {
 ret = snooze;
 }
 }
} << extranious closing brace ends the actual function
 lastrButtonState = rbuttonState;
 lastlButtonState = lbuttonState;
 lastsButtonState = sbuttonState;
 lastoButtonState = obuttonState;
 lastnButtonState = nbuttonState;
 return ret;
}
