<p>which is repeated for 12 months.</p>

<p>There are other values on this form, that when changed causes this loop to be run again, which is fine. I need to reload the values with the result that the other value change causes.</p>

<p>But after making that other change and reloading the page about 4-5 times, I get the dreaded "Stop running script?" error.</p>

<p>Is there a better way? I do have a javascript file that I use and am slightly familiar with jQuery.</p>
