查找代码错误~~

我是初学的~~请帮我看看这个怎么出错了~是在红色标记出的错,报的是 error c0031:syntax error
另外这个是建的全局函数,请问一下新建全局函数是在 declare global variables 里建吗??
要是不是,请指点一下!谢谢
int i,j
windowobject lwo
uo_skin lole
//
if not isvalid(awin) then
return -1
end if

//
for i=1 to upperbound(awin.control)
if awin.control[i].typeof()=olecustomcontrol! then
lcd=awin.control[i].classdefinition
if lcd.name="uo_actskn43" then
lole=awin.control[i]
exit
end if
end if
next

try
if isvalid(lole) then
if not fileexists(askin) then
lole.object.removeskin()
return 0
end if
else if not fileexists(askin) then
end if
awin.openuserobject(lole,-200,-200)
end if
catch(runtimeerror r)
return -2
end try

try
awin.control[upperbound(awin.control)+1)]=lole
lole.object.loadskin(askin)
lole.object.applyskin(handle(awin))
catch(oleruntimeerror orte)
return -4
catch(runtime rte)
return -5
end try
return 1
