I am tring to get the code right that will move a control into the empty space when clicked only if the button is adjacent to the empty space. I am having trouble testing for a button residing to the left, top, bottom, right of a clicked button.

Steven,

You have to think outside the box. He's my stab.. but don't forget, there are dozens of ways to skin a cat..

Each position for a button should have an address: 1 through 16. Create a validation lookup table:
Btn_Address N(2), Valid_near N(2)
1,2
1,5
2,1
2,3
2,6
3,2
3,7
etc.....

Each button should have a position property. (HINT: create a new button class) Each time a button gets moved, the position property should be updated. Prior to moving a button, valididate the destination by doing a seek:

SELECT Add_Valid
SET ORDER TO Adr_Validate  &&  [Btn_Address*100+Valid_near]

lnCurrent = 5
lnTarget = 6

IF SEEK(lnCurrent*100+lnTarget)

  * button move code here (use the array as stated in the previous post)

ENDIF
