@J. D. Yet another rookie mistake. While the code was correct, I had forgotten to disconnect the relevant repeater fields from the database. They were still connected with no filter. This connection seems to override the code. Once I added the display==true filter to my database connection, things work as desired. Thanks JD for your attention.

I verified that display is boolean. The live db only has four items currently; three display==false and one display==true. but all four are displayed.

@Elizabeth Scott This may help get you in the right direction, until Wix Support replies. https://stackoverflow.com/questions/39603446/why-is-this-symbol-showing-up-on-chrome-and-not-firefox-or-edge

thanks. I will try that. What if I just wanted to jump into the database itself and nullify the date? Is that possible?

After a lot of trial and error following the myriad divergent suggestions here, I settled on this setup, which works for me: // GET WIX DATA READY import wixData from 'wix-data'; // WHEN PAGE READY $w.onReady(function () { // workshops $w("#dataset8").onReady( () => { // when repeater is ready $w("#repeater5").onItemReady( ($w, itemData, index) => { const monthNames = ["JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC"]; const startDate = itemData.startDate.getDate().toString(); const endDate = itemData.endDate.getDate().toString(); const startMonth = monthNames[itemData.startDate.getMonth()]; const endMonth = monthNames[itemData.endDate.getMonth()]; const startTime = itemData.startTime.toString(); const endTime = itemData.endTime.toString(); const startTimeDisp = startTime.substring(0,5); // returns hh:mm const endTimeDisp = endTime.substring(0,5); // returns hh:mm const trial=itemData.startDate; // FORMAT DATE TEXT OUTPUT PER ABOVE CONSTANTS $w("#text39").text = startMonth + " " + startDate + " - " + endMonth + " "+endDate; $w("#text52").text = startTimeDisp + " - " + endTimeDisp; ...etc.

Thanks, Anthony. I'm a WordPress/PHP guy, and this Wix/js stuff is baffling to me. Is there something specific in the code I shared that might be problematic? The page in question has six repeaters, but the data behind them - in total - currently represents less than a dozen records. I shudder to think how long it will take once the datasets fill out. I will have a look at ForEachItem, assuming it behaves differently from getCurrentItem. And I'm going to play around with the suggestions in that post you shared.

Ah. Found it. Answer is NO.
