Lab Testing - Error message when inputing data for Split Sieving

Urgent Help!

I'm having serious problem with a project that is due!

I'm inputting data for Sieve Analysis (Split Sieving) but I keep getting this ERROR MESSAGE: Wt Fine Tested must be less than the weight retained on sieve. I'm stuck and I REALLY NEED to find a way to get pass this.

Am I entering the data wrongly? Am I receiving wrong data from the lab? Is there something I could do? Can anyone help with the process of Split Sieving so I can counter check and make the guys in the lab did it right and my problem isn't from the values I received? ALL HELP WOULD BE GREATLY APPRECIATED. THANKS IN ADVANCE!!
