Evaluating Equations Based on Selection !!
Hello;
I would very much appreciate your help. 1) I've developed 12 different (independent) equations y=fn(x), each equation depends on the value of x::cell H30 2) Each equation is given a short descriptive/relevant name for easy selection from a list. For example: mon1 singular:: y = fn1(x) mon2 discontinuity:: y = fun2(x) ............................. mon12 infinite:: y = fun12(x) 3) I used Data Validation in cell H5 to select from the list: mon1 singular, mon2 discontinuity, ..., etc. 4) Now, depending on the selection in H5 from the pull-down list, I need to link the descriptive name to the relevant equation and return its value y to cell H38. 5) A nested IF in H38 would be horrible, very long, and most likely wouldn't work since it would involve more than the allowable max number of loops in a w/s nested IF. 6) On the other hand, having 12 FUNCTION() each representing an equation, the use of w/s CHOOSE() function requires a numerical index!! Is there an elegant way of doing that ?? Thank you kindly. |

Is there an elegant way of doing that ??
What's elegant to one is a mess to another! Give your functions defined names through the menu InsertNameDefine. List those names in a range of cells. Use this list as the source for your drop down. Use this formula to execute the selected function whe A1:A5 is the range that holds the names of the functions A10 is your drop down =IF(A10="","",CHOOSE(MATCH(A10,A1:A5,0),Sum,Avg,Me dian,Max,Min)) The functions *must* be listed in the CHOOSE function in the same order that they are listed in the range A1:A5. Here's a small sample file that demonstrates this: SelectFunction.xls 14kb http://cjoint.com/?czelpt65WW -- Biff Microsoft Excel MVP "monir" wrote in message ...
