Convert Input Text Unique ID to USER type

Hello,

I’ve a form where a Client can choose a Contact (both user).

But I can’t find a Input field with User type …
So when I push the Unique ID of user type into the text type, I can’t save it in the data base.

Any idea ?

Edit :
Input + Repeating user group

Workflow error

Input Content format I don’t find “USER” … only text ???

A searchbox would be a better solution. You can put the type of content as user and show the choices to the users.

In the workflow, you can simply save Contact user = Searchbox A’s value

Thank you for your help.

However, with a searchbox I believe I can’t search within multiple field…

Search in Firstname, name, phone and email at the save time ?
