Change width of subform in code

[GraeagleBill]

I have a situation wherein I want to change the display width of a sub-form. The sub-form's name is "RegistryNamesOnlyFiltered". When I execute the code Me.RegistryNamesOnlyFiltered.Width = 4.6, the sub-form is reduced to a single vertical line on the parent form. When I look at the property sheet for the sub-form, it's title is shown as "Subform/Subreport: RegistryNamesOnlyFiltered". What's the appropriate statement expression to change the width of the subform's display?
Thanks,
Bill

Oops! Wrong units. 4.6 inches = 6624 kips

It is TWIPS and there are approximatelyn 1440 Twips to the inch and 567 Twips to the centimeter. Actually Google knows about Twips.
