Earlier post was not accurate in the code, here it is.

I have a form with a 5-element array in it. I would like to pass this to a modal child form and use the elements in the array to resize the child form.

So in the click event of the parent form's button, I have:
dimension arFormSpec[5]
arFormSpec = ''
arFormSpec[1] = 200 && Height
arFormSpec[2] = 260 && Width
arFormSpec[3] = 290 && Left
arFormSpec[4] = 70 && Top
arFormSpec[5] = ThisForm.txtPick.Value
do form UserChild with arFormSpec

And then I made a form property on the child modal form called
arFormSpec[5]

And in the init method of the form I have
ThisForm.Height = arFormSpec[1]

But when I run the parent form I get an error - NO PARAMETER STATEMENT IS FOUND

What did I miss?
