The error says you can't convert a string to an integer. In your two lines, you're taking strings and trying to assign them to integer variables, which, as the error message implies, you can't do.

I'm not certain what you're trying to do, but don't forget that when you assign one variable to another, the variable that you want to change goes on the left, and the variable whose value you want to put in the other one goes on the right.

have a look at the 2 functions:

 int.Parse
 int.TryParse

if you're guaranteeing the string is parsable to an int, then you can just use int.Parse.

int.Parse will throw an exception if the text cannot be Parsed where as int.TryParse will return false.

 MyPort = int.Parse(MyPort2.text);
 
 int result = 0;
 if(int.TryParse(MyPort2.text, out result))
     MyPort = result;
