Getting error

Hello Amritesh Gupta  you're missing the comma for your value attribute after the if condition statement  and before the save into attribute, Hope this is helpful.

Hi Kilaru,

Thanks for your response, I am still facing some difficulties with my code. 

Here I am attaching my full code please guide me how to resolve it.

The error I am getting is "Expression evaluation error: Syntax error. Details: Expression evaluation error at function a!columnLayout parameter 1: A function expression contains duplicate keywords. Keyword: value."

Hi Amritesh, it looks like you have a duplicate 'value' attribute in your last a!dropdownField. You are also missing a comma after the 'value' attribute in your Total Amounts a!textField. Hope that helps 

You used 'value' attribute two times in one of the dropdown. Also there were comma missing at many places. Here is the code after correcting the syntax errors.
