If you have all the opening and closing braces the compiler might be
complaining because you don't have a sure return. This is not normal for a
compiler but I don't know what compiler your using. So you can try putting
a return at the end of the function right before the last } and that should
do the trick.

Odd, I put all the braces in my original email. I opened the method, two
for loops, an if statement, and an else statement and closed them all. My
bn, on which I wrote that message, must have not liked it that I put them
all on separate lines; it seems to do odd things with punctuation just
before a new line if that punctuation is not connected to a word.
Have a great day,
Alex

Both "for"

your "if" and
