Hey Guys - Has anyone ever experienced this? Material.ByName accepts input from code block in blue and doesnt for code block in purple with both code blocks containing strings.

Hi,
What is the Code Block coming from, can you expand your picture to show more of the script?

[Azubike_Ononye]

It is coming from an excel file.

Is there a possibility of and ‘Whitespace’ in the excel data?
