Forms :: Requerying Subreport On Tabbed Control - Show Related Data

I have a form with a tabbed control on it. The tabbed control has 4 tabs that each have a report on them. When I select a company name on the main form, I requery these 4 reports to show data related to that company.

For some strange reason, 2 of my reports requery with no problem, and 2 of them give me a message that the report can't be found. Here is the code:

Code:
Private Sub cboCompanyName_AfterUpdate()
On Error GoTo cboCompanyName_AfterUpdate_Err
' DoCmd.SearchForRecord , "", acFirst, "[CompanyID] = " & str(Nz(Screen.ActiveControl, 0))

' After selecting a company, requery the subreports to display the appropriate data

' These 2 work

Forms!frmCompanyHistory!RptCompany_Projects_Brief.Requery
Forms!frmCompanyHistory!RptEmployeesSpecificCompany.Requery
'These 2 Fail
Forms!frmCompanyHistory!SubRptCompany_Payback.Requery
Forms!frmCompanyHistory!SubRptCompany_Revenue.Requery

'Other things I've tried

'Forms!frmCompanyHistory!TabCtl66!SubRptCompany_Payback.Requery
'Me.TabCtl66!SubRptCompany_Revenue.Requery

As a side note, if I chose the company, say "ok" to the error, and then go run the queries that these reports are based on, I get the correct records. Also, if I chose the company and run the 2 failing reports standalone, they work fine, so I know the problem isn't the reports or the queries themselves.

I have also checked and rechecked for any spelling mistakes and have found none. I should mention that the error message is "Programs cannot find the field 'SubrptCompany_Payback' referred to in your expression".
