Error when filtering HRU

[Arantxa Ortiz]

Dear QSWA+ users,

I am trying to create HRUs when I get this error (see image).

I have created my own usersoil table, because the ones that were there were too general so I found all the data I needed and i created the usersoil table attached in the email. 

I have no problems creating the HRU, but when I try to filter them (it doe snot matter what type of filter) i get the error of the image. What does this error mean? What can I do to solve the problem?

Thank you in advance

Arantxa
