| hi von ??? |
| sehr sehr viel code... aber leider keine tabulation drin :(. Das macht den code unlesbar.. |
| von ??? |
| Ich weiß, aber da ich einmal meinen Code von der Festplatte verloren hatte und anschließend den gesamten Script hier aus dem Forum wieder rauskopieren musste, sind alle Tabs verschwunden, und ich habe mir bisher nicht die Mühe gemacht, wieder welche reinzumachen. Könnte ich aber demnächst trotzdem mal tun... |
