Hello AnkitG,

The second half of the "Arrays and Clusters" tutorial linked here will walk you through modifying individual cluster elements:

Getting Started with NI LabVIEW Student Training Module 5: Arrays, Clusters, and Text Based Nodes

http://www.ni.com/white-paper/7530/en/

I strongly recommend reading through that tutorial as well as any others you have time for, as this is fundamental concept in LabVIEW and you should have at least a basic understanding before developing complex applications.  If you have a current NI SSP contract, you should also have access to online self-paced training.

It looks like you've already been able to unbundle the element you want to modify, now you just need to branch the cluster wire and rebundle your modified value using the bundle by name function.  Refer to the tutorial linked above for additional information on modifying clusters.

Best Regards.

Bundle By Name

I know this is marked as solved but:

Do you have to unbundle and use substring? Is there any reason you can't just bundle by name with the new value going into the appropriate string input? The results are the same in the snippet below, but the top way uses less code. Or am I missing something?

If you want to replace the entire string, your simpler solution is fine.

The old solution might be needed if there is an existing string and you want to replace part of it. (and in that case, I would ise an IPE structure anyway).
