Get Values out MRVS in a Flow Script

[Meloper]

I have 3 MRVS on a Record Producer

1. i already use Get Catalog Variables

2. i use a for each loop for 2 of the MRVSs

For the 3 MRVS i just need the String Values for a Description Field.
This MRVS has 1 Variable "year".

Maybe user creates 3 rows with values 2017,2018 and 2019.

in one of the for each loops (Step2) i know only need the 2017.2018.2019 as a String in the Description, how can i do this?

Hello @Meloper, 

in your for loop, in each iteration you can update the Description field with the already existing description + the year of the current loop. This way, your Description will look accordingly after each loop iteration. After the last loop the Description will look like required.  
1. Loop: --> Description = 2017
2. Loop: --> Description = 2017 2018
3. Loop: -->Description = 2017 2018 2019

Please the following Flow designer screenshot how to achieve this below. 

I hope this helped!

Greetings,

Unfortunately, I need the string value inside a fixed text.
i also can't run the MRVS in a for Each.
Because we are already in another For each loop of another MRVS.

Hi,

Are you using flow to set values?

You can use Record producer script and use below logic to populate description:

var mrvs= producer.mrvs_variable; // access the MRVS variable
var totalRows = mrvs.getRowCount();
var description = '';
for (var i = 0; i < totalRows; i++) {
description = description + mrvs.getRow(i).getCell('year').getCellDisplayValue() +', ';
}

no, i dont use the flow only to set value.
I use a for each loop do open a new task for every row in 1 MRVS.
and for each new record created by this loop, if have to set a description.
In this discrption, i need also the values another MRVS, but not row for row.
text + rows form mrvs (,) + text
