Rollup: counting single specific records in field with multiple record links


#1

Hello,
i am trying to find a solution for following task:

I got 2 tables.
Table 1: "Polls"
Table 2: “Workers”

In Table 1: "Polls"
are all the polls we created this year as one record per poll.
In those polls records I have a field with multiple linked records .
(its all the workers that participate in that specific doodle poll, linked from table “Workers”)

Now in the Table 2: "Workers"
i want for each worker to create a field,
that counts the total participation of him/her in those doodle polls .
E.g. we had in Table1: “Polls” 10 polls during this year,
he/she participated in 5,
so this field should show “5”

Thats a rollup, i guess, that needs be able to read, whether a specific record (of worker) is found in the multiple record field.
…I am now stuck with the formula.
My approach was to create a rollup Column for each workers record
containing an IF-Formula,
sort of : IF( FIELD with multiple linked records contains this worker , create sum of all his participations)

Is there a way to achieve this?
