Can't create new simple query

[GW]

HI,

I try to click the pull down table/queries from the simple
query wizard then I hit this message :-

Microsoft Access

The expression On Got Focus you entered as the event
property setting produced the following error:The text you
entered isn't an item in the list.

* The expression may not result in the name of a macro, the
name of a user-defined function, or [Event Precedure].
@ There may have been an error evaluating the function, event, or macro.

Appreciate it if someone could help me.

Thanks
