Trouble selecting checkbox on website - ajax

Question

after a couple of days of trying, and failing, i need some help please.
I'm trying to select a check box on an website, but it doesn't seems to work as I want to.
the check box is part of a row in a table, together with some other data. The idea is that I log in on the site (http://www.apf.asn.au), go to the table, find the numbers I need from my excel sheet, and select the box that is in the row the number is found.
the log in and navigate to table part is working ok, but I can't find the proper way to select the box.
code from the site:
<div class="table">
<div>
<table class="table APFGrid StudentsSearch"
id="ctl00_ContentPlaceHolderMainNoAjax_gvJumpRecordsList"
style="border-collapse: collapse;" border="1" rules="all" cellspacing="0"
<tbody>
<tr>...</tr> 'Header
<tr>
<td>
<span class="clsSelect">
<input
name="ctl00$ContentPlaceHolderMainNoAjax$gvJumpRecordsList$ctl02$chkSelect"
id="ctl00_ContentPlaceHolderMainNoAjax_gvJumpRecordsList_ctl02_chkSelect"
onclick="javascript:ToggleCheckBoxSelection;" type="checkbox"></input>
</span>
</td> 'Box need to check
<td class="Name">...</td>
<td class="Name">...</td>
<td class="DateBirth">...</td>
<td class="APFNum">...</td> 'Number I'm looking for
<td class="JumpType">...</td>
<td class="DateBooked">...</td>
<td>...</td>
<td class="Name">...</td>
</tr>
<tr>...</tr>
Etc.
I use this code:
'Get APF Number from Pipe
xNr = "20819334"
'Search Number online
Dim i As Integer
i = 0
For Each Row In APFtable
If i = 0 Then
Set Member = Row.getElementsByTagName("th")
Else
Set Member = Row.getElementsByTagName("td")
End If
i = i + 1
On Error Resume Next
If xNr = Member(4).innerText Then
'Check the corresponding checkbox
Exit For
End If
Next Row
to compare the number, in my example: xNr, to the numbers in the table. But I can't figure out how to check the box.
I tried this code:
Name = "ctl00$ContentPlaceHolderMainNoAjax$gvJumpRecordsList$ct" & 100 + i & "$chkSelect"
Set Check = IE.Document.GetElementsByName(Name)
If Not Check Is Nothing Then
Check(0).Click
End If
end all the other ways I could find in other forums to get it to work, although this came closest to working. which means that it worked when I hard-coded the name in the variable with out the "calculating position" part.
can someone advice me on my problem?
Much appreciated

Answer 1

Member(4).parentElement.getElementsByTagName("input")(0).Click
Should do it if the checkbox is the first input element on that row.
