Iterate through loop to storeText or sourceExtract based on class

I’m trying to loop through and store all the tracking number text fields on a page (about 100 on a page). Each id is unique so I can’t iterate through something like loopCount + 1. Here’s the element:

<a href="https://www.website.com/ship/tr/Events?itemid=234472029152&amp;transid=1989887018" class="trackingOverlay">9405508205497426618222</a>

I want to save “9405508205497426618222” to csv. It is always to the right of the class ‘trackingOverlay’

I tried something like sourceExtract xPath=//*[trackingOverlay">*</a]@{!loopCount} and that would iterate through all the matches on the page until exhausted. But that didn’t work I kept getting “#nomatchfound

Here’s my code:

`{
  "Name": "tracking number scraper",
  "CreationDate": "2020-10-16",
  "Commands": [
    {
      "Command": "bringBrowserToForeground",
      "Target": "",
      "Value": ""
    },
    {
      "Command": "comment",
      "Target": "open // https://www.website.com/sh/ord/?filter=status:ALL_ORDERS",
      "Value": ""
    },
    {
      "Command": "store",
      "Target": "1",
      "Value": "loopSuccess"
    },
    {
      "Command": "store",
      "Target": "1",
      "Value": "loopCount"
    },
    {
      "Command": "while_v2",
      "Target": "${loopSuccess} > 0",
      "Value": ""
    },
    {
      "Command": "storeText",
      "Target": "xpath=//*[contains(@class,'trackingOverlay')]",
      "Value": "!csvLine"
    },
    {
      "Command": "if_v2",
      "Target": "!${!statusOK}",
      "Value": ""
    },
    {
      "Command": "store",
      "Target": "0",
      "Value": "loopSuccess"
    },
    {
      "Command": "end",
      "Target": "",
      "Value": ""
    },
    {
      "Command": "executeScript_Sandbox",
      "Target": "return Number(${loopCount}) + 1;",
      "Value": "loopCount"
    },
    {
      "Command": "csvSave",
      "Target": "eBayTrackingNumbers",
      "Value": ""
    },
    {
      "Command": "end",
      "Target": "",
      "Value": ""
    }
  ]
}`

This loops through and saves to the csv file fine, but it only saves the first text over and over. It doesn’t iterate through the different elements. I also tried these two lines instead of the storeText line but couldnt’ get it to work

`{
          "Command": "comment",
          "Target": "sourceExtract // \"trackingOverlay\">*</a>@{!numberCount}",
          "Value": "trackingNumber"
        },
        {
          "Command": "comment",
          "Target": "store // {!trackingNumber}",
          "Value": "!csvLine"
        },`
