Do you mean a simple list of staff like in field "formular"?

Hi, Rafael. Put this Code in a formula-field and try it. It´s another CSS with cool round corners like I haven't seen them anywhere, but you can copy the old form into the new, if you don't like it. Mirko

let selStaff := record(STAFF,number(this.Staff_Choice));
let cntRes := cnt((select event_staff_join)[staff = selStaff]);
let content := "
<style>
td,th{
    font-size: small;
    background-color: rgb(230,230,220);
    font-family: 'Courier New';
    padding: .1em 1.5em .1em 1.5em;
}
/*dynamic round corners*/
tr:nth-of-type(1) th:nth-of-type(1)  {
      border-radius: 2em 0em 0em 0em;
}
tr:nth-of-type(1) th:nth-of-type(4)  {
    border-radius: 0em 2em 0em 0em;
}
tr:nth-of-type(" + (cntRes + 1) + ") td:nth-of-type(1){
    border-radius: 0em 0em 0em 2em;
    }
tr:nth-of-type(" + (cntRes + 1) + ") td:nth-of-type(4){
    border-radius: 0em 0em 2em 0em;
    }
</style>
<table>
        <th>detail</th><th>staff</th><th>date</th><th>type</th>
        " + ((select event_staff_join) order by 'Event Detail'.Date)[staff = selStaff].("
        <tr>
            <td>" + 'Event Detail'.Name_Event + " </td><td>" + replacex(staff.Name_Staff, "[a-z\s']+", "") + "<td>" + 'Event Detail'.Date + "</td><td>" + 'Event Detail'.Type + "</td>
        </tr>
        ") + "
</table>
";
html(content)

I misunderstood you, you meant the existing table on tab "Tablet". There is an array of names.

let cntRes := cnt(select 'EVENTS DETAIL');
let content := "
<style>
td,th{
    font-size: small;
    background-color: rgb(230,230,220);
    font-family: 'Courier New';
    padding: .1em 1.5em .1em 1.5em;
}
tr:nth-of-type(1) th:nth-of-type(1)  {
      border-radius: 2em 0em 0em 0em;
}
tr:nth-of-type(1) th:nth-of-type(4)  {
    border-radius: 0em 2em 0em 0em;
}
tr:nth-of-type(" + cntRes + ") td:nth-of-type(1){
    border-radius: 0em 0em 0em 2em;
    }
tr:nth-of-type(" + cntRes + ") td:nth-of-type(4){
    border-radius: 0em 0em 2em 0em;
    }
</style>  <table>
    <thead>
        <tr>
            <th> Staff </th>
            <th> Name Event </th>
            <th> Date </th>
            <th> Type </th>
        </tr>
    </thead>
    <tbody>
        " + ((select 'EVENTS DETAIL') order by Date).("
        <tr>
            <td> " + join(Actv_Staff_join.staff.Name_Staff, ",") + " </td><td> " + Name_Event + " </td><td> " + Date + " </td><td> " + Type + " </td>
        ") + "
    </tbody>
</table>  ";
