I am having problems tryiing to populate my text box with a field from a query. I have tried everything. Basically I want to be able to put a value in my text box, on my form, using the DLookup function. I am looking up values from my query and get a data type mismatch error. My query is;
SELECT tbl_Historical_SPN_Trades.spn_name, tbl_Exclusion_Type.Exclusion, tbl_Historical_SPN_Trades.Date_Added, tbl_Historical_SPN_Trades.spn_id AS SPN
FROM tbl_Historical_SPN_Trades INNER JOIN tbl_Exclusion_Type ON tbl_Historical_SPN_Trades.[Exclusion Type] = tbl_Exclusion_Type.Exclusion_ID;
And My DLookup is
strSPNValue = txtSPN.Value (Which will equal something like 0020397)
txtExclusion.Text = DLookup("[Exclusion]", "Sel_Historical_SPN_Lookup", "SPN = " & strSPNValue)
Now SPN is a text field in my table, as is Exlusion. I can not see why the error is occuring?
