Paramater Pick-Up Problem

[mickeymouse]

I understand that to pass a paramater from one page to another 
from a call in a function I must have "?param=myparam" following my page id.

e.g.
    function ancesterF(myparam)
    {location.href='mypage1.php? param=myparam';return false;
    window.open(location.href); return false;} 
    
and to pick-up the paramater in the called page, I need to use:
      $getmyparam=$_GET['param']; 

However, it doesn't work.  
The resulting pick-up is "myparam" instead of the 
value of "myparam" which is "10006"

Does anyone know how to pick-up the value passed?

I can't find anything about this in PHP documentation.

Many thanks

The clue is in what actually happened! 

?param=myparam (as in index = value)

$getmyparam=$_GET['param']; (apply index value to $getmyparam)

returns 'myparam' (the value)

myparam should be 10006.

Its treating myparam as a string, not parameter variable, you have to separate the variable from the string

{location.href='mypage1.php?param='+myparam;return false;
    window.open(location.href); return false;} 

'mypage1.php?param=' is string part, while +myparam will now join the value of myparam to rest of string

Thank you dsonesuk.  It works perfectly (all the time when we do it right)

I'd like to give you points but don't know how.  Can't see anything on the page that would allow me.
