How to set string variable to empty string?

[tinjaw]

I am building a string by concatenating several strings together. Before I do this I want to set the value of the variable to an empty string. Not null, an empty string.

If I use a Set String Value action, I cannot leave the String Value empty as it considers this an error.

What is the proper way to set a sting to an empty string?

Would using a simple space be acceptable?

If not, you can just remove the [RequiredField] above the variable definition and save it as a new script.

Actually, its attached.
