Unique ID doesn't work/increment. Every time I submit a form, it keeps displaying the same submission ID Starting number.

Will generate duplicate IDs if people submit at approximately same time. There's two reasons for this: 1) There's no database (e.g. auto increment) or file system lock mechanism to prevent updating the number at the same time, so it's not unlikely enough. 2) The number is generated when the form is generated, so it's actually not even remotely unlikely.
