Magic Button - Open form to specific tab?

Referencing: https://community.quickbase.com/quickbase/topics/custom-buttons-for-tabbed-forms-save-next-tab-save-same-tab

I've used a modified version of this how-to guide to create a 'Save Button' inside a form that modifies a couple of hidden fields, then saves all current changes, and then re-opens the form in a targeted tab.

My (Formula Rich Text) button code is as follows:

[CBSc1]
& "Modified.JS"
& [CBSc2]
& [CBSt - SKW]
& "Button Text"
& [CBE]

My variable codes are unchanged from the original, but listed as follows:

• [CBSc1]  -  <a href='javascript:($.getScript("https://PLACEHOLDER.quickbase.com/db/PLACEHOLDER?a=dbpage&pagename=

• [CBSc2] - "));void(0);

• [CBSt - SKW] - ' class='Vibrant Tall' style='font-size:14px; color:white; background:#6BBD57; white-space:nowrap;'>

• [CBE] - </a>

On my Modified.JS page:

$("#_fid_10").val("Unlock");
$("#_fid_11").attr("checked", true);
var nextTabLink=$("li.ui-tabs-selected").next("[style!='display:none']").children("a");
$("#saveAndKeepWorkingMenuOption").click();
var noErrorDialog=$('#qbDialog').length==0;
if( noErrorDialog ){
$("#tab_t2_link a").click();
location.assign('#navTop');
};
