Not able to add value to a column

[Vijay_Zutshi]

Hi

I have a node Group Loop Start with following data

I have added my workflow below:-

I am not able to add a country name to the output from Row Filter. My Row filter has following output: -

I have used Joiner node may be I am using wrong conditions but it is not adding the name of the country.

Please advise

Thanks

I have used Joiner node may be I am using wrong conditions but it is not adding the name of the country.

If you look at your output from Row Filter, your “Countries” column is of Double type. This is different to your input in the Group Loop Start node which is of String type for the “Countries” column.

Somehow during the process the type changed? To Join them, you need similar column types.

Thanks for your reply. That is a good catch my friend. So after column filter I added another node - Number to String and changes Countries back to String. So my Row Filter output is

Then added a Joiner node as follows: -

but still my joiner node output is

Please advise

Thanks

I’ll let someone else handle this, since I don’t understand why you would consider String columns as input to a Linear Correlation in the first place.
