Problem opening subform

[sue gray]

I have a main form (frmTxPlanHxMH) that opens a subform (frmTxPlanMH) from a
command button. frmTxPlanMH contains 5 subforms laid out in pages. My
problem is that when I open frmTxPlanMH none of the 5 subforms are there. I
see the tabnames but not the fields on the forms. But when I close
frmTxPlanMH and then open it from another command button to open it in read
only the forms show up.

tblclient - pk - clientid
tbltxplanmh - pk txplanMHID
one to many - clientid from tblclient to clientid from tbltxplanmh

Here's the code for the command buttons. Thanks for any help it's greatly
appreciated.

Private Sub AddTxPlan_MH_Click()

On Error GoTo Err_AddTxPlan_MH_Click

Dim strDocName As String

strDocName = "frmTxPlanMH"

DoCmd.OpenForm strDocName, , , , acAdd, , Me!clientid

If IsNull(Forms!frmtxplanmh!clientid) Then
Forms!frmtxplanmh!clientid = Me!clientid
End If

Exit Sub
