Can some one help me on this

I don'r know if it is very dificult to make this, but for me I need to input directly
the product Cost and that is the normal.
And the second Field: Gross Margin $ instead of the Markup Percent, that need to be automaticly calculated.

I've allready tried to make this to work, but without any success.



Does some one manage to link this with the mod "quick updates" or "inventory report" ?


Thanks !!!
