Passing Variables or Database Parameters to forms and tables...

As our Ministry database gets bigger I need to find a way to story
variables or parameters so that rather than change 15 forms and
reports I could change one variiable possibly stored in a table and
change the whole database at once by changing that value... for
example it took an hour to change the logo on each individual form and
report yesterday.. Couldn;t I just store the name and location of the
logo possibly in a table... and reference all of the object properties
to it...

I'm not sure how I would do it and what the syntax would be to
retrieve it but it would sure be easier....

Any ideas.. or help

Thanks
