Sum textbox value in footer RRS feed

  • Question

  • Greeting
    i have 3 textbox value in footer of my report
    i want make total (sum) for tow of them
    so when i try to make total with them give me this error

    The Value expression for the textrun ‘.Paragraphs[0].TextRuns[0]’ refers to more than one report item. An expression in a page header or footer can refer to only one report item.

    i used those code for sum but none of them working


    i also tried this


    but even give me error

    is there any idea fro solve this problem
