Row height in a subform

[jean]

Hi

When I have a continuous form containing 3 fields, i can change the
height of rows with a button containing this code:
[Field1].height = 480
[Field2].height = 480
[Field3].height = 480

So the user is able to see more text. When finish user can click
another button containing this code:
[Field1].height = 240
[Field2].height = 480
[Field3].height = 240
[Detail].height = 240

Works fine when the button are on the form (Form header)

Now I have a Main Form "Employee" (single) containing a continuous
subform named "EmployeeSub"

What I am trying to do is: to change rows of the subform with a button
on the Main Form

I have try many different codes without success

Can someone help me

Thanks
