Please use the formating tags to make your posts clearer. I have difficulties distinguishing your error or warning messages from your own question.

Please also post the code snippet where you get this message. We can't guess without seeing your code. From what I can see in your post, it seems that $VAR1 is not numeric and you are comparing it numerically to 2 (!= is a numeric comparison), which seems to be the source of the error or warning. I can't say more, since I have no idea what $VAR1 is supposed to contain.
