Your if is incorrect

IF %id%==1(

First of all, it needs a space before the parenthesis, then you are making a wrong comparison, since the "==" operator only works when comparing strings and you're trying to compare with a number. What you can do is as follows:

if %id% EQU 1 ( <--- IF only parses numbers when one of the compare-op operators (EQU, NEQ, LSS, LEQ, GTR, GEQ) is used. 
if "%id%" == "1" ( <--- To force a string comparison. The == comparison operator always results in a string comparison.

IF %id%==1(

is incorrect syntax.

IF "%id%"=="1" (

should work. The space before the ( is required

since id may or may not have a value, or may contain spaces or other separators or awkward characters that batch finds distasteful, enclose it in "quotes" to remove the sensitivity to (empty, contains separators) [but not, unfortunately to "unbalanced quotes]

The two sides of the == operator need to exactly match - so the quotes must be included both sides.
