Redirect iRule with URI redirection and pool distribution

Seems like there might be a syntax somewhere that is causing error when I compile the iRule. This is the error I get:

Code
01070151:3: Rule [/Common/test_redierct] error: 
line 1: [parse error: missing close-brace] [{
if { [HTTP::uri] contains "/read.pdf" } {

} elseif { [HTTP::uri] starts_with "/Mypersonal/formula" } {

} else { 
switch -glob [HTTP::uri] {
"/page1*" -
"/page2*" -
"/page3*" -
"/index*" -

}
default { 
pool green 
}
}
}]
