Sorry , I don't know what I am doing wrong :


IF THISFORM.grid1.Height = 100
THISFORM.grid1.Height = 10 <- program stop here
ELSE
THISFORM.grid1.Height = 100
ENDIF


VFP7 prompt me error message :

error with grid1 - height : Expression evaluated to an illegal value.


What wrong with my program? Try out whole day.... :(


TIA.
