Filtering in dynamic value expression in variable input

[Vaibhav2]

Hello there, I have a variable 'Sort' which lets the user select the measure on which he can sort the table. To perform this task, I used a variable input extension with Sort as the variable and dynamic values expression. Inside the expression, I wrote the below mentioned syntax but it is not working. The gold flag is a dimension on which I want to apply a filter and Revenue is the measure. The error that it shows is 

Error in expression :- '}' expected

Can someone please help

Expression :- 'sum({<gold_flag={''Base''}>}Coupon_Revenue)~ Base Sales|'
