Using a dropdown to filter a gallery

[MrNguyen]

Good morning!

I have a gallery which gets filtered by a few dropdown items: GM, ERP, Module. The code below is currently working as expected:

SortByColumns(
    Filter(_L1Records,
        If(!IsBlank(dropGM.SelectedText.Value), GM = dropGM.SelectedText.Value, true) && 
        If(!IsBlank(dropERP.SelectedText.Value), ERP = dropERP.SelectedText.Value, true) && 
        If(!IsBlank(dropModule.SelectedText.Value), L1_Type = dropModule.SelectedText.Value, true)
        ),
    "GM", Ascending
)

From within the gallery I have two text labels called validate_Diff_vs_Recon and validate_Unrecon_vs_Prov which returns either "Yes" or "No". On the outside of the gallery I have a new dropdown object called dropMismatchType and I'd like to filter the gallery for where either the text labels are "No".  I have tried this and it's giving me a circular reference error:

    SortByColumns(
        Filter(_L1Records,
            If(!IsBlank(dropGM.SelectedText.Value), GM = dropGM.SelectedText.Value, true) && 
            If(!IsBlank(dropERP.SelectedText.Value), ERP = dropERP.SelectedText.Value, true) && 
            If(!IsBlank(dropModule.SelectedText.Value), L1_Type = dropModule.SelectedText.Value, true) &&
            If(dropMatchType.SelectedText.Value = "Mismatch", Filter(g_Summary.AllItems, validate_Diff_vs_Recon.Text = "No" || validate_Unrecon_vs_Prov.Text = "No"))
            ),
        "GM", Ascending
    )

Is there a way for me to filter / search based on a field value within the gallery? Any help would be greatly appreciated!

You can't reference the items in the gallery to filter_L1Records to create the items that go into the gallery.  If the labels for data for validate_Diff_vs_Recon and validate_Unrecon_vs_Prov are referencing columns in _L1Records then you should be able to use those columns in the Filter formula.
