I have the below formula on my gallery which mostly works. I have 2 comboboxes and 1 text input box.
Goal: filter the gallery based on selections in either of the comboboxes or text input box. The formula works when the comboboxes and text input box are empty (it returns the list in its entirely). Additionally, the gallery will filter when text is in the text input box. However, my issue comes when making a selection in a combo box - the gallery will not filter.
Additional Info: I have a clear selections button that OnSelect resets all the comboboxes and text box. Upon clicking it successfully removes the selection. Not sure if this is causing an issue as it resets.
If(IsBlank((TextInput1) && IsEmpty(ComboBox1.SelectedItems) && IsEmpty(ComboBox2.SelectedItems)),'Standards, Disclaimers & Disclosures', Filter('Standards, Disclaimers & Disclosures', 'Review Element(s)' in ComboBox1.SelectedItems.Result || 'Subject Matter or Content Topic(s)' in ComboBox2.SelectedItems.Result || TextInput1.Text in 'Required Language'))
