Linked Report Margins (2005 Edition)

Hello, I've been trying the suggestions in the link below, and without success.

This is supposed to allow us to build a linked report with these properties already set. This post works for a linked report that is already deployed. I want to set the properties on the report as I'm deploying the linked report. The instructions listed don't seem to work, it gives type errors and other related things when I try this approach, has anyone else had any luck doing this?

It says:
Error : rsElementTypeMismatch (The value provided for the PageHeight
field is not valid for its type. It cannot be converted from a string value to
the type that is required.)

What do I do to get around this? I tried changing it to a number, but no luck. I'm trying to do this in rs.exe:

Dim props(7) As [Property]
props(0) = New [Property]
props(0).Name = "Description"
props(1) = New [Property]
props(1).Name = "Hidden"
props(2) = New [Property]
props(2).Name = "PageHeight"
props(3) = New [Property]
props(3).Name = "PageWidth"
props(4) = New [Property]
props(4).Name = "BottomMargin"
props(5) = New [Property]
props(5).Name = "TopMargin"
props(6) = New [Property]
props(6).Name = "LeftMargin"
props(7) = New [Property]
props(7).Name = "RightMargin"
props = RS.GetProperties(basereportpath, props)
RS.CreateLinkedReport(name, parent, basereportpath, props)
