Submission : How to pass the entry ID into the URL [RESOLVED]

Dear all

I use 2 forms Form1 and Form2
On form1 submission, i would like to pass the following parameters
email={Email:1}&entry_id=???

How to replace the ??? by the ‘entry ID’ value to be collected by form2 ?

Thanks in advance for your help
Regards,
Eric

{entry_id} contains the entry_id value

email={Email:1}}&entry_id={entry_id}
