license，可以把實驗放到網路上去收集資料，但軟體費用很高就是了。<br /><br />Flash或許什麼都可以作，但你要先讓人相信你作出來的實驗是準確的，不是嗎？不妨先看看你領域的文章是用什麼東西作實驗的。 <p><a href="http://feedads.g.doubleclick.net/~a/EYWNamk0ISureTpgeAZTkCuzJBE/0/da"><img

那我在請問一下喔<br /><br />因為你的方法真的是OK的耶<br /><br />但是我發現他會呈現出這樣的結果<br /><br />id level #ofA #ofB<br />1 A 1 0<br />1 A 2 0<br />1 B 2 1<br />2 A 1 0<br />2 B 1 1<br />3 B 0 1<br /><br />也就是只有第三筆id 才能呈現出確實的資料<br />所以想請問您 該如何讓id=1的那三組 都呈現<br />#ofA=2<br />#OFB=1呢??<br /><br />真的非常謝謝你<br />你真的幫了我超大超大的忙 <p><a href="http://feedads.g.doubleclick.net/~a/w5dgzRcuMjIBAOKsoxEnJwDve1I/0/da"><img
