Last Attempt On This One

I have a form that opens after the user selects a "trade" from the combobox list on the "Trade parameter panel" form and clicks on a button. The text in the combobox becomes the parameter of the query that the "Trade" form opens from.
Once the form opens there is a textbox which is part of the heading i.e. "all employees listed as Welders" but instead of having all the trades in the list with an "s" on the end, i want to dynamically add the "s" to the end of say "welder" or whatever trade is selected.

The usual & "s" doesnt work because record source is dynamic and i dont want to have a seperate "s" textbox floating about due to the varying lengths of the trade string.

Below is the main part of the query

WHERE(((Trade.TradeID)=[Forms]![Trade parameter panel]![Combo4])AND((EmployeeCert.Level)=[Forms]![Trade parameter panel]![Level]))ORDER BY Employee.Surname;

Thank you in advance
