Validate Range Against Numerous ConditionsDec 7, 2007
I have a VERY complex custom data validation formula that is getting crazy. I thought it might be easier to use a user defined VBA function to handle it, but was unsuccessful.
I was able to write a VBA User Defined Function & use it within my spreadsheet to derive the value of another cell, as follows: =IF(OR(ISBLANK(B12),myValidation(B12)),"OK","NG")
I tried using it as a Custom Data Validation on the cell itself (=myValidation(B12)), and I get an error: "a named range you specified cannot be found".
Can the function be used in this way or could someone suggest another way of handling this?
