adding from drop down to database

[grlayouts]

Ok i have a script where if you select one of the drop downs, if you have the cash in your credits it will update the database as you having one of them.

 

HOWEVER every time it goes on it gives the player a steak house without clicking on it.

 

anyone?

 

<? print "<form method=post action=enterprises.php?view=add&step=add>Build  <select name=building><option value=DrugFactory>Drug Factory</option><option 	value=SteakHouse>Steak House</option><option 	value=CarLot>Car Lot</option><option 	value=Passport>Passport</option></select>. <input type=submit value=Add></form>";
if ($step == add) {
if ($building = 'DrugFactory') {
if ($stat[credits] <30000) {
print "Sorry mate, you don't have the cash.";
} else {
	mysql_query("update players set drugfact=drugfact+1 where id=$stat[id]");
		print "Building added."; }}}
	 else 
if ($building = 'SteakHouse') {
if ($stat[credits] <60000) {
print "Sorry mate, you don't have the cash.";
} else {
	mysql_query("update players set steakhouse=steakhouse+1 where id=$stat[id]");
		print "Building added."; }}
