Math using IF statement syntax error

[vbcoach]

Hello all.  Having trouble with doing an IF statement using a math operator.  Seems simple enough, but I keep getting a syntax error.

 

I have a sports league, who's fees are based upon the number of (extra) players on a team.

    $intPlayers is a variable number derived by a loop of the number of registered players on a given team.

    $intBsize is the base league size given based upon the league registered (2, 4, or 6)

 

I am trying to come up with a mathmetical PHP statement that will determine if the number of (extra) players over the "base" number.  Once that happens, I can charge a fee per player over the team base amount allowed.  For example, if a 6's league registers 8 players, they need to pay for those additonal two players.

 

So here is my code with the syntax error:

$plyrCount = $intPlayers - $intBsize
  {if $plyrCount<0 then $plyrCount = '0'}

$xtraPlyrs = ($plyrCount * 40)

 

I have tried a bunch of variations, but nothing seems to work.  If the value of $plyrCount is a negative number, then set $plyrCount to zero.

 

Can anyone help please?

if ($plyrCount<0) $plyrCount = '0';

Still getting syntax error

[smoseley]

$plyrCount = $intPlayers - $intBsize;
if ($plyrCount<0) $plyrCount = 0;
$xtraPlyrs = $plyrCount * 40;

That worked, thanks!

(now I am getting an undefined variable message - more digging)

 

Thanks!
