Expression "Wrong" Syntax Error"

[PersOne]

Hi, 

An expression that usually worked, does not anymore Syntax Error :

thisComp.layer("Dad's Birthday/Dad's Birthday.chproj").transform.zPosition - 1 => TypeError Cannot read property zPosition of undefined 

If I take out the "- 1", it's accepted ?!

Thank you
