    It's hard to explain what it does... but yes it does matter if it's checked or not.

    What it does is to toggle "" around that peice of input on and off (expression = no ""). (It's explaining what that does thats hard).

    Well heres an example:

    gotoAndPlay("myFrame");

    (expression box not checked) This sends the movie to a frame labeled 'myFrame'.

    While:

    gotoAndPlay(myFrame);

    (expression box checked) Sends the movie to to the value of the variable 'myFrame'. ('myFrame' can be a number or a string).

    This isnt really the best example, but I hope you get the idea.

    Does this help at all...

    // example

    anotherVar = "that text"; // not an expression because we're using quotes

    thatVar = " and this text"; // again, expression box is not checked; you still have quotes

    thisVar = anotherVar + thatVar; // thisVar is equal to the value of anotherVar plus the value of thatVar ("that text and this text"); this is an expression (box is checked, removes the quotes, evaluates the expression)
