Searching using multiple criteria

[Dazzla]

I have a button with this code attached

Dim SearchStr2 As String
SearchStr = "[PROTECHNIC_NUMBER] = " & "'" & Forms![FRMPATIENT]![Frm_ICP_Select].Form![Protechnic_Number] & "'" _
And "[ICP_Code]" = Forms![FRMPATIENT]![Frm_ICP_Select].Form![ICP_Code]
DoCmd.OpenForm "FRMASSESMENTHEAD", acNormal
Forms!FRMASSESMENTHEAD.Filter = SearchStr
Forms!FRMASSESMENTHEAD.FilterOn = True

If the button is clicked it should open the FRMASSESMENTHEAD form where the Protechnic Number (which is a text field) and the ICP Code(which is numeric) is the same as the ones on the current subform.

It works great if just using one of the criteria but when i put the and command in and then add the second criteria i get an erroer message saying

Run-time error '13':

Type mismatch

hope this makes sense and can anyone help

Just noticed i missed the 2 of the second SearchStr but still get the same error.
