VBA code to load parameters for a popup display in FTView

Using FTView SE (Local Station) I am searching for VBA code as a noob to load a parameter file based off an operator input.

Operator types a number into a numeric input field (tag is a memory tag called 'input')

I want to now load a FTView parameter file (called 'Parameter' 1 through 64)

If the operator inputs 3 for example I want parameter file Parameter3 to load.

How do I code this in VBA?

Application.ShowDisplay "Display Name", "/PNameOfParameterFile" or something similar? Just not sure how to incorporate the operator input tag.
