converting a recipe from extract to all grain

I'am having problems using the converting tool I have watched the tutorials but they show converting from all grain to extract I want to go the other way. I can't figure out how to change the old recipe box to extract, any help is appreciated.

What type of extract is in the recipe.  If is a light LME or DME (such as Breiss), I would just change the recipe to all-grain and substitute the extract for a base malt.  Then increase the base malt up to get near the same OG, IBU and color as the original recipe.
