Getting Syntax error in OP54 while maintaining formulas for parameters

Hi,

While configuring cost estimates with qty structure, I have created 3 Parameters for 3 activities. But, when I am maintaining formulas for parameters, I am getting error like "Syntax error between column 2 and 3"

I am not able to understand where I am making mistake.

Any help would be greatly appreciated.

Thanks again.
