Error Message

When using the point dispersion sample extension with a geocoded theme, the following error is returned:

"Can't convert string to number: Number Null"

  2. Select the Start editing option under the table menu.
  3. Open the query builder.
  4. Enter the following into the expression box:

    Code:
    ( [Av_status] = "U" )

  5. Click New Set.
  6. Delete those records from the table.
  7. Select the Stop editing option under the theme menu.
  8. Click yes to save your edits.
  9. Run the point dispersion extension.
