ActionScript Errors

Hi! I am having some problems. When I try to publish my fla, it pops up with these errors:
Error Symbol=Main Bar, layer=Main Bar, frame=12:Line 6: Statement block must be terminated by ‘}’
if(this._parent.Mask._currentframe = 1){
Error Symbol=Main Bar, layer=Main Bar, frame=12:Line 10: Syntax error.
this._parent.Mask.play()}
Error Symbol=Main Bar, layer=Main Bar, frame=12:Line 5: Statement block must be terminated by ‘}’
on (release) {
Error Symbol=Main Bar, layer=Main Bar, frame=12:Line 10: Syntax error.
this._parent.Mask.play()}
Total ActionScript Errors: 4 Reported Errors: 4

My code, however, doesn’t show any errors when I check the syntax:

 on (rollOver) {
this.arrow.play()}
on (rollOut) {
this.arrow.gotoAndStop(1)}
on (release) {
if(this._parent.Mask._currentframe = 1){
if(_root.People.Mask._currentframe=1){
_root.People.Mask.gotoAndPlay
this.play()
this._parent.Mask.play()} 

I have no clue what I’m doing wrong. Some help, please!
FLA file is 236.2 KB. Sorry, the FLA is big, so you must own a .rar unzipping agent.
