Power Platform Community Forum Thread Details

I would like to use the Lookup function in Powerapps as follows-

UpdateContext(
    {
        lvarResetRequestDetail: LookUp(
            lstPwdResetRequest,
            fldPwdChangeApprovedByID=""
        )
    }
)
 
It doesn't give any result but doesn't show any error. Please help as I stuck at no where. The table is in Sharepoint and the Field is Text type. It doesn't allow to use IsBlank or IsEmpty. Nothing is set in the Field Default Value.
