[Notice: Trying to access array offset on value of type null in]

Those two lines assume that something exists in $cellt when it, apparently, does not. Hard to tell why or what's going on from just this code...

Is everything behaving the way you expect it to, besides the notices?

 

everything seems fine, I am attaching the whole code, maybe your eyes will see the bug

Hello, I have inherited a website, but I can't find the php version, and when I run the website on 7.4 php, I get a lot of errors, maybe you can help?

58       while ($row = sqlsrv_fetch_array($result))
59        {
60            if ($row[1]!=$st)
