HI guys, another numpty question, sorry but what is wrong with this?
if ((anval < switchlevel)&&(x > 5)); digitalWrite(2, HIGH);
else (digitalWrite(2, LOW));
I’m getting ….
Compilation error: 'else' without a previous 'if'
If I leave out the &&(x > 5) condition all is ok.
Many thanks for any advise here
Thanks Paul, I said it was a numpty question, appreciate your help!
But do you understand why it was wrong before?
To be honest, not really, I tend to just bumble along working from other peoples examples and generally get where I want to be in the end. The syntax has always been a black art to be fair
That extra semicolon was ending the if-statement. The digitalWrite() after it would have been executed regardless of the condition, which would have been really confusing if the code had compiled and uploaded. Because the if-statement was ended, the else had no if-statement to belong to, hence the error message.
The semi colon ';' is the end of a statement, so in your case it ended the if statement (prematurely)
Ah yes I’ve got it now, at least until the next time 
Thanks again.
