Execution of any php script

when i try  to call a php script by using [onshow;script=phpfile.php]
in a html , that php scripts in turn calls a html file which displays the data. The result is not shown in the specified block .The scripts gets executed soon .
What should i do?

How, two successiv posts with the same problem :)

You just have to add parameter 'getob' to get the result.
  [onshow;script=phpfile.php;getob]

Well i have tried that, but the output is not shown  in proper place

Can you post or send the source of your 'phpfile.php' file?
