Return Last Number In Range

I need a formula/tip that will return the last non-blank item in a list or array. I am updating a worksheet each month with that month's metric and want the end user not to have to scan to the right to see the current value, but see it at the front of the worksheet. For example:

A1 is labeled "Current Value"
B1 : M1 are labeled "JAN" : "DEC"
B2 : G2 have values 45, 54, 32, 65, 14 & 23 respectively
H2 : M2 are blank

I need a formula in A2 that returns the last non-blank item in B2 : M2. In this instance, 23. When I enter a value into H2 (the "JUL" column), I want A2 to reflect that new number. =IF won't do, due to the 7 nest limit. I've seen this solution before but despite arduous searches, I can't find it.
