Combining two columns into a single columns eliminating blanks

I've attached a sample.

As you'll see I've applied a formula in Column V and arrayed down.

{=IFERROR(IFERROR(INDEX($K$9:$K$59,SMALL(IF($K$9:$K$59<>"",ROW($K$9:$K$59)-ROW($K$9)+1),ROWS($K$1:$K1))),INDEX($L$9:$L$59,SMALL(IF($L$9:$L$59<>"",ROW($L$9:$L$59)-ROW($L$9)+1),ROWS($L$1:$L1)-COUNTIF($K$9:$K$59,"<>")))),"")}

It is picking up Column K then there's 14 blank rows then Column L appears, the 14 blanks are from the first 14 rows before a Column L number appears.

How can I eliminate all blanks and zero's???? and have one continuous Column V of numbers?
