How to hide fields within subpage / page

Here is a great sample of Page.Activate peoplecode that will hide fields within a page or subpage. You can also use a group box around a subpage to hide all the fields within that group box.

&admin = "N";
SQLExec("select 'Y' from psroleuser where roleuser = :1 and rolename = 'RoleName'", %OperatorId, &admin);
If &admin = "Y" Then
DERIVED_TL_WEEK.TL_TA_CALC_PB.Visible = True;
End-If;

/*** Within Sub Page ***/
TL_LINK_WRK.TL_TEXT_LBL5.Visible = False;
TL_LINK_WRK.TL_TEXT_LBL1.Visible = False;
TL_LINK_WRK.TL_TEXT_LBL2.Visible = False;
