:X
cls
echo --------------
echo Connect Four X

echo CHOOSE A COLUMN

echo  1   2   3   4   5   6   7

If you are entering a string with a set/p , then there's no saying that the data entered doesn't contain Spaces . The way to get over that is to "enclose the strings on both sides of the comparison operator in quotes" - that is, double-quotes 'not single quotes'

IF syntax is if string1 operator string2 action.

You need

if "%possiblyemptyvariable%"=="1" goto ...
