i made a workaround so this problem isn't relevant anymore

the file itself is approx. 15megs, so that's difficult, but i'll post some
formulas

in sheet Vekeersaanbod in cfell D29
=IF(Routekeuze!D29=1;INDEX('Verkeersaanbod
(totaal)'!$B$3:$J$27;MATCH(D$5;'Verkeersaanbod
(totaal)'!$B$3:$B$27;);MATCH($B$3;'Verkeersaanbod
(totaal)'!$B$3:$J$3);TRUE)*VLOOKUP(Tijdwinst!D29;H ulptabellen!$C$4:$G$105;5);0)
(a similar formula is in each cell in this sheet till ceel T600something)

The vlookup returns a percentage that might change, and goes:
=(C$3+$B5)*Reistijd!$F$29
C3 and B5 yield a percentage times F29. This F29 is the variable which will
change now, but for which I need to record the change and draw a graph...

The Routekeuze!D29 formula goes:
=IF(AND('Routevoorkeuren (m tol)'!D29<'Routevoorkeuren (m
tol)'!E29;'Routevoorkeuren (m tol)'!D29<'Routevoorkeuren (m tol)'!F29);1;0)

The D29 i refer to here is:
=IF($C290;(($C29*Reistijd!$E$12)*(Tijdwinst!E29-Tijdwinst!D29));"")

Reistijd!E12 is a set value that might change, but that not relevant to the
question
TijdwinstE29 and D29 are the results of formulas, but they won't change either

Does this help?

...
i've build a model in excel.
on the basis of a few variables i made quite a number of sheets. one
variable i had to keep constant, otherwise i would need 3d tables. now
that
the model is almost done, this one variable needs to change.
it needs to take discrete values between 0 and 5 (for example, and in
steps
of .25) the change of this value has to be calculated in the model and the
result needs to be in a table. every result (which will be 4*6*something)
need to be visible, as they will be used in a graph.
(am i still clear?)

now, how do I change that one value and allow excel to draw the graph?
(if you need more information, ask your question and i will try to answer
them)
