Tab Over on ALL pages

Greetings,
I am currently running Thesis 1.8.5 on my site here http://www.texashomeloanpro.com

I used the forum here to fix the "tab over" problem on my homepage by pasting the following into my custom functions folder:

add_filter('gform_tabindex', create_function('', 'return 2'));

My question: how do I make this fix apply to ALL of the pages on my site?

Thanks,
G

Hey Rob,

I pasted the code from the link into my custom functions folder and it did somewhat help the tab over issues on my site pages; however, when I can't seem to "tab-over" in the correct order (i.e. the cursor skips around to different forms on the page). Here is a good example: go here http://www.texashomeloanpro.com/dallas-home-loan-options/ and try tabbing over.

Any other suggestions?

Thanks,
G
