*** ERROR # 1000 *** in the input data:

Hi! I'm currently doing a coupled thermal structural analysis but when I try to get results I get the following errors: 

*** ERROR # 1000 *** in the input data:

Incorrect data in field # 3.

Expected INT > 0 or blank, found INTEGER (0).

*** ERROR # 1000 *** in the input data:

Incorrect data in field # 4.

Expected REAL > 0 or blank, found REAL (0).

I don't understand what it means and for what I read it is caused by forgetting to assign material to a property which I checked and I did or forgetting to assign a property to a component which I also did. Any ideas?

I will attach my file if it helps. Thank you!
