JavaScript in CP600

Hi,

I was trying to get something down with Javascript in CP600 But got no success and found no relevant doc.I have checked the manual for the Panel Builder and there is nothing which is helpful

I have a real value and when that data equal to 1 I need to make it a bit high. This is what I was trying to do as an experiment. I have attached a snip of the js that I have made for it and it is not working.

Kindly check the snip and share the error.
