@yisrael-wix Hi! I need your help.
How do I display an error message in this code:
import wixData from “wix-data”;
$w.onReady(() => {
});
let lastFilterplatfromTheyIntegrate;
let lastFilterplatformName;
let debounceTimer;
export function input7_keyPress(event, $w) {
if (debounceTimer) {
clearTimeout(debounceTimer);
debounceTimer = undefined;
}
debounceTimer = setTimeout(() => {
filter($w(‘#input7’).value);
}, 50);
}
function filter(platformName, platfromTheyIntegrate) {
{
if (lastFilterplatfromTheyIntegrate !== platfromTheyIntegrate || lastFilterplatformName !== platformName) {
let newFilter = wixData.filter();
if (platformName)
newFilter = newFilter.contains(‘platformName’, platformName);
if (platfromTheyIntegrate)
newFilter = newFilter.contains(‘platfromTheyIntegrate’, platfromTheyIntegrate);
$w(‘#PODPlatform’).setFilter(newFilter);
lastFilterplatformName = platformName;
lastFilterplatfromTheyIntegrate = platfromTheyIntegrate;
}
}
}
Basically, this is a code for a repeater. What I want is to show error message when there’s no result. 
Thank you!
