Insert a Control in a string path?

[Promice]

Hello, I want to insert a numeric control in in a string path. Suppose my string path is DEMODS/%d/HARMONIC and i want to insert an control so that my value in %d changes in accordance with the input from the Numeric Control. This is what i mean 

For example, When i select 1 in the Demod Selection control my string should be DEMODS/1/HARMONIC and when i select 10 in Demod Selection Control the string should be DEMODS/100/HARMONIC and so on. I am a begineer in labview so its a bit of problem for me. Thank you in advance
