In the last image you posted, the points' variable names are p385 and p386 but in the script body they're being referred to as passwordPointp385 and passwordPointp386, so that is why you got the reference error. As Craig said you'll want to use the actual hexidecimal password (or if it's just a number remove the 0x before the number for decimal) instead of 0xdeadbeef, which is just one of the many things which can be spelled in hexidecimal.
if the customer change the current password, how we will get the new hex value?
I will appreciate so much your support
You will be told the value they changed it to, I would expect, then you could change it. If you want to, you could store the password in a point and then send the value of the point. Then when the password changes you just set a new value to the point.
