MIN Appears As 0 With Blank Cells

I am trying to use a MIN() function on a row of numbers; the row is not completely full (some days data was not recorded) and when I have a blank cell, the result in the MIN() frame is 0.0. This is unless of course I have a negative number (which I don't, but for the sake of argument)

This is my current function:

{=MIN(IF(AND(MOD(COLUMN($D10:$DL10),5)=1,CELL("CONTENTS",($D10:$DQ10))0),$D10:$DL10))}
It works like:
Take every 5th column starting at the second.
Try to ignore any cell that contains 0. (This I am trying to get to filter out the empty cells; I have tried ISBLANK(), ISNUMBER() and still get nothing)
Then return the cell to the MIN() function.

That is the long winded thing of it all, basically it can be summarized as this:

{=MIN(D10:DL10}
I have also tried some other code which I was told did the same thing essentially (which it does) but is shorter and nicer:

{=MIN(IF($B$5:$DQ$5="Q*",$B10:$DQ10))}
Which will check for the proper heading on each Column.

These functions work fine with AVERAGE/MAX as far as I can tell, just not with MIN().

As a side note, none of the cells leading up to this function contain "0".
