Calling a function

[Junior]

I have a parameter query (based on IDfield in a data entry form)
the query passes values to a function - the function checks the variables
and opens a msgbox if there is a problem with the data entry.
Now- how do i call this function or query from the data entry form so that
the msg box will display and not the query results.?

Imbed it in you Function with an IF statement.

If this = that then
msgbox "message"
end if
