So I want to create an if statement that will not allow the input of a non-integer into STDIN. I tried two things that did not work:

The first: 


if ($numind!=int) {
    print "**This is an invalid entry!", "\n", "Please try again.**\n"
+;
    goto START;
    }

The second: 

if ($numind!=int(1..10000)) {
    print "**This is an invalid entry!", "\n", "Please try again.**\n"
+;
    goto START;
    }

[download]

The first error states that I have an uninitialized value, which makes sense but the second one, instead of limiting a decimal, limits all input, integer or not, and prints the "Invalid entry" output.

Any help is appreciated,
