2 separate problems: Find Minimum and a count from a range of numbers while ignoring blanks.

I've got two cells:  First is called:  MINA.   The second cell is called:  CNTA.

I've got one column of numbers:  Cells are named SR-1, SR-2, SR-3, SR-4....SR-31.

I need a calculation that finds the minimum value in the range[SR-1:SR-31] that I can use in the "MINA" cell.  This calculation needs to ignore blanks because not all cells in this range may contain data.

I need a second calculation that counts the number of cells with data in the range[SR-1:SR-31] that I can use in the "CNTA" cell.  This calculation also needs to ignore blanks for the same reason.

I needed an average calculation as well and managed to get that to work, for reference, here is that calculation:  This calculation was typed in my "AVGA" cell.  This one works great with no problems!

-----------------------

// Initialize variables

var i, v, num = 0, sum = 0;

// Loop through the input fields

for (i = 1; i <= 31; i++) {

v = +getField("SR-" + i).value;

if (v !== 0) {

// increment the non-blank/zero field counter

num++;

// add the field value to the running total

sum += v;

    }

}

// Calculate the average

if (num) {

event.value = sum / num;

} else {

// All fields are empty, so set to blank

event.value = "";

}

------------------------

I just can't get anything for a Minimum calculation and for a Count calculation to work.  Remember...they need to be separate calculations--I cannot combine minimum and count in one calculation.

Thanks in advance anyone who can help!!
