Coolsoft NSISDialog Designer question on generated dialog

I have used Coolsofts tool to design a dialog, however when I try to compile it in my own install script I am getting !include: error in script: "DialogTest1.nsdinc" on line 29.

Line 29 is: !insertmacro MUI_HEADER_TEXT "Configuration" "Config"

Could someone please assist me in resolving this error?

sorry I found it. I was missing the "!include MUI2.nsh" declaration.
