I tried everything and I couldn't be able to fix it...

 

Line 159 - 161

 

                       $stat1+=$i['inv_qty'];
		$stat2+=$i['itmsellprice'];
		$stat3+=$i['itmsellprice']*$i['inv_qty'];

$stats = $var['array'];

I don't understand?

[Zettieee]

+= This operator isn't been used right.

Just use =

[The Coder]

From what I think his saying is...

Change to this:

 

$stat1 = $i['inv_qty'];
$stat2 = $i['itmsellprice'];
$stat3 = $i['itmsellprice']*$i['inv_qty'];

Thank you guys! :)

The error is now fixed!

Without first understanding what those variables are used for, simply changing += to = would not be a good idea.

What you should've done *above* those three lines was add this:

$stat1 = 0;
$stat2 = 0;
$stat3 = 0;

 

What the code was doing is this: It was trying to add on to a non-set variable
