need to expand popup query list

[f_disk]

On my main screen I have a button that I press and it pulls up a
pop up box...in the box you type in one item and hit ok then
the query goes and gets the results.

My quesion:
how do it make it so when I click the button the pop up box
has lets say four areas where I can enter different items and
then it goes and gets all four...or three or whatever I need ?

thanks...

ok how about this

How do I do a form where I can enter 1 to 6 items and then it will
go and retrieve the information on each one.
Note that some of these items may have more than one listing such as:

mt100 pepsi
mt100 coke
mt100 chips
mt25 sugar
mt26 water

Once it has found the items it needs to list them like shown above with
lets say the ingredients next to them or whatever I have put in the table.

thanks
