result not showing when looping - sql

Question

I'm doing a powershell which runs through a loop to get result from an sql query with different parameters. the issue is only the first run of loop has a result. the rest all blank result which should also show some result.
$Days = #(90,60,30,15)
$Start = 0
$End = 0
$Affiliation = 1
for ($i = 0 ; $i -lt $Affiliation.Count ; $i++) {
for ($i = 0; $i -lt $Days.Count ; $i++){
if ($Days[$i] -eq 1) {
$End = $Days[$i]
$Start = 0
write-host "Start/End r:" $Start $End
}
elseIf ($index -eq $Days.Length) {
$End = $Days[$i]
$Start = 0
write-host "Start/End m:" $Start $End
}
else {
$End = $Days[$i]
$Start = $Days[$i+1] + 1
write-host "Start/End s:" $Start $End
}

Because you use in both forloops the same variable $i this will be overwritten all the time. Change the name of one of them.
Bad:
for ($i = 1; $i -lt 11; $i ++)
{
('First for loop: ' + $i)
for ($i = 1; $i -lt 11; $i ++)
{
('Second for loop: ' + $i)
}
}
First for loop: 1
Second for loop: 1
Second for loop: 2
Second for loop: 3
Second for loop: 4
Second for loop: 5
Second for loop: 6
Second for loop: 7
Second for loop: 8
Second for loop: 9
Second for loop: 10
Good:
for ($i = 1; $i -lt 11; $i ++)
{
('First for loop: ' + $i)
for ($x = 1; $x -lt 11; $x ++)
{
('Second for loop: ' + $x)
}
}
First for loop: 1
Second for loop: 1
Second for loop: 2
Second for loop: 3
Second for loop: 4
Second for loop: 5
Second for loop: 6
Second for loop: 7
Second for loop: 8
Second for loop: 9
Second for loop: 10
First for loop: 2
Second for loop: 1
Second for loop: 2
