could you give some quick translations on what some of those words are in english please. I'd love to help but my german (i think its german) is a little rusty.

[armijn]

its all about this part of the code:

teller = 0;

if (e.getSource() ==knop1 && (teller==0))
{
if
(invoer1 !=("armijn") && (invoer2 !=("wachtwoord")))
teller=teller+1;
else
teller=0;
}

if (e.getSource() ==knop1 && (teller==1))
{
if
(invoer1 !=("armijn") && (invoer2 !=("wachtwoord")))
teller=teller+2;

else
teller=0;
}

if (e.getSource() ==knop1 && (teller==2))
{
if
(invoer1 !=("armijn") && (invoer2 !=("wachtwoord")))
teller=teller+3;

else
teller=0;
}

if (teller==3)
knop1.setEnabled (false);

teller is a int that gets information about if the login name ("armijn") or password ("wachtwoord"). i want to get this teller (int) work, so when the password/username is wrong 3 times that it will all block the textfields/buttons etc. i know its fault but it just doesnt work in all ways. i tried everything to get this work. so now just a quick conclusion: i want to put a action on a button (knop1). so if you press that button the int (teller) is gonna count till its 3 and if its 3 it blocks all buttons so you can do nothing

hmm i cant even get the code to compile without errors like else without and if statement
