check the form filter property on the data tab
That message refers to the 'temp query' used for the row source of a combo or listbox on a form.
As it indicates, the row source has been deleted so code dependant on that triggers the error.
Open the Search form in design view, find the control (List5) and do one of the following
1. Restore the missing row source
2. Delete the control or replace it
3. Remove the code in form load that depends on that.
If none of those apply or work, your form may be corrupted
