Excel2003 ...

Range (H3:H13) contains Formulas returning a space ("")
Cell H15 contains ... =IF(OR(D1="",COUNTA(H3:H13)=0),"",SUM(H3:H13))

Cell H15 returning correct value when values in Range (H3:H13) manually
entered ... but, now that I have Formulas in this Range returning a space
("") the COUNTA(H3:H13) part of my formula is returning "11" ...
Consequently, the SUM portion of my Formula is returning "0" when I wish
Formula to return a space ("")

What adjustment do I need to make? Thanks ... Kha
