Answer: It is most likely that you are trying to replace a String with an Integer. The #Replace function won't work with Integers, it expects the oldValue String to be replaced by the newValue String.

[Notes from Visual Studio Intelisense]: A #String that is equivalent to the current string except that all instances of oldValue are replaced with newValue. If oldValue is not found in the current instance, the method returns the current instance unchanged.
