Regex Checkpoint Javascript HELP!

Hello, 

Can anyone help me how to use regular expression for checkpoints, I've been trying to use it, but my checkpoint keeps failing. I think I am doing it wrong. 

I am trying to check if the property of an object returns an integer. 

My code is something like this:

aqObject.CheckProperty(Object.Test, "Value", cmpMatches , RegExp("\d+")) 

Result: 

Thanks.
