[Genome] ucsc genome browser custom track problem

[zxu]

hi,

previously, I put several custom track our webpage, today, I add a new 
custom track like following line.
browser position chr16:10000000-12000000
track name="OtherGenes" description="Other Genes" visibility=pack 
color=150,136,0
chr6    29070541        29081072        NM_001010877    0       -       
29070756        29075276        0       6       
1801,105,561,82,168,309,        0,3948,4701,8727,9112,10222,

but when looking at genome browser, all the previous tracks are showing 
like before, but the new Othergenes track wont show, even looking at 
"Custom Tracks" Tab, it won't show "OtherGenes", try to figure out 
what's wrong?
