} //actually I convert squarefeet from feet and inches

Answer 4

how do you guarantee that all text boxes contain a valid double to convert and no other text?
closing } is missing.
are all text boxes accessible?

Answer 5

use variables
make smaller steps
use {} the are not mandatory but increase the readablity of your code.

what do you want to do ?

Answer 6

can you give example data ?

is the mathematical precedence correct ?

Answer 7

I dint try but go on positive way to enter all data in correct format.

((convert.todouble(textbox1.text)* convert.todouble(textbox2.text)) *
((convert.todouble(textbox3.text)*
convert.todouble (textbpx4.text)) / 12)*
convert.todouble(textbox5.text)).tostring()

kindly note don't go on syntax error.

thanks ..
