The question was raised several times with no result - INDIRECT does not work in this case. In Excel EVALUATE function may help, but only using VBA, what also not very usefull.
Range A3:A6 contains conditions, Range B3:B6 - corresponding formulas's texts, E1 contains Condition Selector (Data Validation List in this case). The formula in D9:D12: =indirect("B"&MATCH($E$1,A:A,1))
The question is - how to transfer(convert) the text from B3:B6 to D9:D12, to make them proper formulas?
