In SharePoint 2007, how to display a value of a field from another page?
Similar to the below:
<SharePointWebControls:FieldValue id="PageTitle" FieldName="Title" runat="server"/>
but it's from another SharePoint page.
SharePointWebControls:FieldValue displays values from the current SharePoint context, the current list item.
To display a value from another page, i suggest using the Content Query Web Part, to query the page you need.

Select the fields you want to display, the list you want to lookup, and item/page you want to select
<ViewFields>
<FieldRef Name="Title" Nullable="True" Type="Text"/>
</ViewFields>
<Lists>
<List ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}"/>
</Lists>
<Webs Recursive="True" />
<RowLimit>1</RowLimit>
<Where>
<Gt>
<FieldRef Name="Created" Nullable="True" Type="DateTime"/>
<Value Type="DateTime"><Today OffsetDays="-7"/></Value>
</Gt>
</Where>
