The problem is that textbox2.text is empty and maths blocks don't work with empty text blocks

textbox2 is filled by the user,so there is value

I believe this is the case that a user pressed button2 with out entering a value. You could add and if statement to check if textbox2 is empty and if textbox3 is not equal to 0 (cause you can not divide with 0) then do ....

Textbox2 is the desired weight and textbox3 is total weight. Still the problem . The operation yail divide cannot accept the arguments: ,["0"]

you have to understand, that a calculation is only possible for numeric values, but not for empty strings
just add some data validation, for example

if is empty desired weight
then display a notifier "please enter a desired weight"
else do the calculation
