Don't mind on these input radio buttons, especially in second form cuz those first 5 are copied from first form

[Rifts]

you need to use

 

if( isset ($var))

{

    do/show this

}

else

{

  do/show this

  }

[BlueSkyIS]

... and....

 

// if($strana = "") should be

if($strana == "")

also tried and same

if (isset($_GET['strana'] == ""){

[Rifts]

if (isset($_GET['strana] == ""){

 

should be

 

if (isset($_GET['strana'] == ""){

[quelle]

if (isset($_GET['strana] == ""){

 

should be

 

if (isset($_GET['strana'] == ""){

it is, soz this code wasnt copied from dreamweaver just typed it cuz it would be faster than searching for it 

[BlueSkyIS]

not quite.

 

if (isset($_GET['strana']) &&  $_GET['strana'] == ""){
