single function for multiple buttons

Hi there

My problem is that I am trying to use the following functions on 10 different logo movieclips. Each logo movieclip has a popup up box (another mc) within its timeline with a description in. When I hover over the logo movieclip i want it to call the forward frames function and on hover out call the rewindframes function.

function forwardFrames() {

    onEnterFrame = function () {

        if (_currentframe != 15) {

            nextFrame();

        } else {

            stop();

            delete this["onEnterFrame"];

        }

    };

}

function rewindFrames() {

    onEnterFrame = function () {

        if (_currentframe != 1) {

            prevFrame();

        } else {

            stop();

            delete this["onEnterFrame"];

        }

    };

}

However i am trying to do all this on the main timeline and the only way i can think to make it currently work is if i do the following for every logo mc which, surely there is a better way:

symbol_1.onRollOver = function() {

     symbol_1.onEnterFrame = function () {

          if (symbol_1._currentframe != 15) {

                    symbol_1.nextFrame();

          } else {

               symbol_1.stop();

               delete this["onEnterFrame"];

          }

     };

}

symbol_1.onRollOut = function() {

     symbol_1.onEnterFrame = function () {

          if (symbol_1._currentframe != 1) {

               symbol_1.prevFrame();

          } else {

               symbol_1.stop();

               delete this["onEnterFrame"];

          }

     };

}

Any advise would be much appriciated, thankyou
