190107: Text fields can be selected, but must only contain numeric values greater than zero. Characters or values less than zero will cause the tool to fail.

Description

Text fields can be used, but they can only contain positive (greater than zero) numeric values. If negative values or nonnumeric characters are used, the tool will fail.

Solution

Open the attribute table of the input features and verify that the field contains no nonnumeric characters and that all values are greater than zero. If any nonnumeric or negative values are found, change the values or delete the row.
