Web - Server

Hello,
I have trouble manipulating the insert statement to show desired information in my portal after login,
the problem the paper seems to work only when the error is coming back which is not the case here as I got only request failed when errors happen,
I somehow have been able to inject at the end of insert statement but I think I need string concatenation here to insert some more info in the injected field.
am I wrong?
I tried sub queries but there always errors.
I don’t know what I am doing wrong here any hint could be helpful.

Thanks
