b = "'" + TextBox2.Text + "'"
x = "'" + TextBox3.Text + "'"
d = TextBox4.Text
n = "'" + TextBox5.Text + "'"
Dim s2 As String
s2 = "insert into users2 ( num , name1 , pass , add , phone ) " & " values ( " + m + " , " + n + " , " + b + " , " + x + " , " + d + " ) "

1. You need to encapsulate values you want to insert into ''

. "values('" + m + "', '" + ...

2 I don't understand & operator between two parts of query in the beginning
