in reply to Template toolkit Adding Values to Variable

[% totalprice + ff %] <---- 2 ------>
That doesn't change the value of totalprice. Did you mean GET totalprice = totalprice + ff perhaps?

    Its my mistake i am changing it right now. i didnt write the proper code when i was makig simplified version to make my question more clear. but in fact it is [% totalprice = totalprice + ff %]. it seems like as i answered to " CountZero " , 'totalprice' variable become private when it is inside the

    [% FOREACH %]
    block because i printed the value inside the block and it does change but as soon it comes out of the block it retain the initial value ( the one before the [% FOREACH %]). i have tried to use [% BLOCK PROCESS %] but it still does not make any differnce. i might need to get the value from the script.

    But in your answer,dont you think it should be 'SET' what i have red in the ' Perl Template Toolkit ' book.

    thanks
      I deliberately used GET because I want to execute the calculation and interpolate it into the text. Without GET, you're chosing one or the other.

        Thanks for clearing that for me. But i am stil stuck. i tried the GET method but still same result. i can get the value out of it in the [% FOREACH %] block but as soon it comes out of block it goes back to what it was before the block started.

        should i assume that in TT ,From [% FOREACH %] block , we cannot export the value which i believe is possible in PERL itself.
