Are ´con tal de que´and ´a condición de que´ interchangeable ?

How do we get lessons to clear from our listing.  I seem to do the lesson, get both test questions correct, but the lesson stays in my list.'

Thanks.

.....antes fue a tontaría. I believe this should be 'lo de que' as 'ir is conjugated, but the answer shown as correct is 'lo de', why?

For those that might be interested...

The adaptation of the famous novel 'One Hundred Years of Solitude' (Cien Años de Soledad) by Gabriel García Márquez has finally arrived on Netflix! 

Another Spanish film that I found very interesting is 'The Red Virgin' (La Virgen Roja) depicting the life of the famous Spanish writer Hildegart Rodríguez. This film is on Amazon Prime. 

Both great films for practising our listening skills. 😀
