Yes, i solved it about 20 minutes ago. At first, under "UPDATE/CALCULATE FIELD", DO was set to "copy a fields value", FROM was set to was the question of the multiple choices and TO was the output field. but it didn't add up. 

I then changed the DO to "calculate a field value" and i saw that  when i clicked on ADD VALUE button, the field for the multiple choice was set "A-Z" instead of "0-9". then after changing it, to set the DO to "copy a fields value" and it start working properly. 

Thank you.
