Error :

Do you have any idea for this problem ?

Thanks you

People are generally reticent to download large amounts of code, me included.
Have you ensured all your references to whatever “now()” is are visible in all tabs?

Have you tried reducing the problem to something that can be posted here?
In reducing the size and working it through, you may find the problem yourself.

It doesn't help that your zip file is corrupt.
