有關expression program問題

[philipcheng]

locator1.extend=locator1.extend/2;
但佢話我錯
系唔系除唔系咁寫？

What are you trying to do with the expression? Are you trying to create a loop?

yes！想做loop 的effect，系唔系唔好用除來計，用for loop 再+ if 來玩會好d?

[stantang]

For loop would be better, but I don't see why your expression doesn't work. What's the "extend" attribute? I assume you added it by yourself, correct?
