Try replaing the code to create your button with the following:
<INPUT TYPE="BUTTON" VALUE="Button Title" ONCLICK="window.location.href='http://something/something.aspx?ID={@ID}'"/>
Replace "?ID=" with the name of your parameter, (e.g. "?Myparameter=")
Replace {@ID} with the column name used for the parameter source (e.g. {whateverparameteriwanttopass})
This worked on my end.
