Strange Issue when creating new level

Hey there I've recently been trying to make a second level in my game basically having the same event sheet and some recurring assets , however upon trying to test it i keep running into this screen which does not allot me to play the level , but it works fine on the previous level and the coding has not been changed at all by myself.

the error message will be enclosed.

It seems like the value X or actually x, doesn't exist.

Not sure if this value is a variable or just the x-value for a certain object not present on your layout, but there is a reference to this value in your event sheet and the value can not be read by javascript.

Well i have tried copying all the assets over from the previous layer which did nothing , its not a variable , i assume its talking about the use of X velocity in the script since i'm using physics , thanks for your reply i appreciate it.

Can you post a capx of this?

OK , I've managed to fix the issue , for whatever reason the collision polygons on the level's platforms were causing the issue as they had for some reason just randomly assigned themselves in places that cause overlaps and this was causing the error.

thanks to all who helped.
