The original MS Excel VBO Run Macro does not have, in its present form, that possibility.
You need to edit or create a new action that allows you to pass parameters.
You can either hard-code the number of parameters you want your macro to take or you can give your code stage a Collection, turn it into an array and pass it as a variant. This way you will have a more generic action and you can pass as many parameters as you want, although you would need to remember to ""handle"" the array inside the macro.
