Script Column Position

I have a column built from a script. I built a button to call the scripted column that works. However, when I attempt to set the column's position in the button code, the button is greyed out and not accessible.

This works:

Set COLUMNSTOGGLE="scp:Column.Generic: Age/TimeSinceModified"

This does not:

Set COLUMNSTOGGLE="scp:Column.Generic: Age/TimeSinceModified"(1+modified)

Any ideas?

The position code needs to go inside the quotes.

...And solved. Thanks Jon!
