Hi,
I'm trying to convert columns from String to Double with the Select tool.
The issue is that the header name changes to Null afterwards.
How can I divide between those two parts?
Thanks in advance
Your assumption is correct so something odd is happening with that file. I've attached a sample file and workflow that looks similar to yours which works fine for me.
Can you post an attachment of a simple example with what it is you are trying to do?
Changing the field type in the Select tool should not affect the name of the field. Could you provide an example of your scenario? An image or attached workflow would greatly help troubleshooting.
