array alignment

[Anonymous]

hello,

im trying to do a parametric ladder family with bars that are arrayed by a formula of height/30 so ill get bar every 30 cm depends of the height, so far so good. but after i create the array,  it doesnt stick to the distance from wall label and then when i change the distance from wall, the bars stay in their places and dont move.

the model of the family is attached to this post. 

please help me fix it

this is a picture of my family before changing distance from wall:

and this is after changing ditance from wall:

You have to lock the 1st and 2nd instances of the array to the vertical reference plane. Create the bar as a nested family so you can lock them more easily.
