Use this code to check if the current user already has an entry in Form B when Form A is submitted. If the user does NOT have an entry in that form, this code will create a new entry in Form B. If they do have an entry in Form B, it will update the entry. This example specifically will populate a field in Form B with the user's total number of submissions in Form A.

If you are using a User ID field, this function is not needed. Use this function if you are collecting email addresses from users who are not logged in, and would like to show an avatar using only the email address.
[25 avatar=40]
25 = the field ID
40 = the size of the avatar

This example will change the format of date fields from the default Y/m/d to d/m/Y when it is exported as a .csv file.
