vb.net adding large sum on variable integer - mysql

Question

I created a queuing system which would display multiple counters and the queue number of the customer and their service group but when I update them, all data looks like the first counter. My update function is refreshed on timer tick so every 1 second it updates the information.
Public Sub updatecountera()
openconnect()
SQLi = "SELECT `counter`, `logconcern`, `logcustcurr` FROM `access` WHERE logstatus= 1 and counter=1 "
SqlRun()
If myData.Rows.Count = 0 Then
countera.Text = "avail"
counteracust.Text = "avail"
counteraservice.Text = "avail"
Else
countera.Text = myData.Rows(0)(0)
counteracust.Text = myData.Rows(0)(1)
counteraservice.Text = myData.Rows(0)(2)
End If
closeConnect()
End Sub
Public Sub updatecounterb()
openconnect()
SQLi = "SELECT `logconcern`, `logcustcurr` FROM `access` WHERE logstatus= 1 and counter=2 "
SqlRun()
If myData1.Rows.Count = 0 Then
counterb.Text = "avail"
counterbcust.Text = "avail"
counterbservice.Text = "avail"
Else
counterb.Text = myData1.Rows(0)(0)
counterbcust.Text = myData1.Rows(0)(1)
counterbservice.Text = myData1.Rows(0)(2)
End If
closeConnect()
End Sub
Every timer tick only the information of countera shows on all counter (counterb, counterc). When I try to include mydata.clear(), it shows an error of "no data row position". How can I get all the counters to update information without compressing all info in 1 sql statement and selecting per data row since it is very messy to do that?
Edited to add SqlRun() method
yes i was missing 'counter' i added it on my counterb but it still shows identical information here is my sqlrun ():
Public Sub SqlRun()
'transfer sql connections
SQL = SQLi
myCommand.Connection = conn
myCommand.CommandText = SQL
'execute adapter commands
myAdapter.SelectCommand = myCommand
myAdapter.Fill(myData)
myAdapter.Fill(myData1)
myAdapter.Fill(mydata2)
End Sub
