I understand

The error came from a simple line
Label96.SetLayout (55% x, y 251%, 14% x, 35dip)

I single quotes a few lines in the beginning
'lbl1.SetLayout (25% x 3% Y, 55% x, 30dip)
'Label1.SetLayout (2% x, y 9%, 25% x, 30dip)
'Lblontwepbin.SetLayout (10% x, y 9%, 25% x, 30dip)
'Label2.SetLayout (12% x, y 9%, 25% x, 30dip)
and the error was gone.
And when I removed the single quotes, everything was okay again
Strange?
