Ok i got a stupid little problem.
I need to calculate a variable from a sql query.
I can echo a variable from the query and it shows for example 22, but i need to multiply it.

So i got:

$old = $query[nValue]; 
echo $old;

it works it shows 20

$old = $query[nValue]; 
$percent = 2;
$multip =  $old * $percent;

echo $multip;

it doens't work and shows 0.

Or:

$multip =  $query[nValue] * 2;
echo $multip;

This shows 2??, so please some php guru can explain me why this doesn't work?

The value nValue is being suggested as a constant without the quotes and I think that is what is messing things up.

echo $query['nValue'] * 2;

No effect, same results.
Thnx for replying though!

The only thing I can think of is dumping $query:

PHP Code:

print_r($query); 


Maybe that will yield some insight into what the issue is.

Hell yeah i figured it out, variable was placed in wrong part needit to place it in the while loop itself for some reason.

Pretty stupid and weird but ok it works now. This can be closed.

Probably a good time to point out that posting more than the code you think isn't working is always better for debugging.
