Set Multivalue Parameter from values Message box outputs

[bronc3buster842001]

This rule retrieves the info I want from the excel sheet. How do I take the values from the message box and make it into a multivalue parameter.

GoExcel.Open("C:\Users\Brian\Desktop\Book1.xlsx", "Sheet1")

For rowNumber = 5 To 37

	If Voltage = 6.3 Then

		If Not GoExcel.CellValue("B" & rowNumber) = "" Then

			MessageBox.Show(GoExcel.CellValue("A" & rowNumber))

		End If

	End If

Next

GoExcel.Close

What version of inventor are you using and Ill redo it so you can open the file

I think you have an issue because you are setting the list and trying to change the parameter at the same time. I would suggest having one rule to create the value list  and one to set them. Or check the workflow your using manually and try and replicate this. A video would be more helpful if you can't figure it out, this will help see where the workflow is falling down.
