How to check if the member exists in essbase cube using IF cond.

Question

Hello,
I have a requirement to validate certain accounts and if they exist or not and use them in calc. We have certain list of percent accounts which have some driver amounts. If the user selects the parent account, it should automatically calc with percent accounts to generate the values for all its children.
The issue is we have lots of accounts and lots of percent accounts, its not that all accounts have the percent accounts. thats the problem.
When I Fix at a high level of accounts, am getting this error which says that member doesnt exists and return empty member set.
Error executing formula for [Revcnt] (line 49): attempt to cross a null member in function [@X]
Its the same even if I use Set Emptymembersets ON;
The script is below,
FIX(@Relative({SelectAccount},0),
"Revcnt"(
IF(@ISMBR(@MEMBER(@CONCATENATE(@NAME(@CURRMBR("Account")),"%"))
Condition ;
ENDIF);
ENDFIX
Is there a command to validate if the member exists in the cube or not???
We are using 11.1.2.1 Essbase on Windows 64bit.

The silly question first:
Why not user dynamic calc for the members you need? When updating the structure, you create the formula. Your verification if a member exists will be done in, for example, a select statement that create the dimension.
Now the complex idea:
Is it possible in your application recreate the script every time you update the dimension?
My example:
Here we have a cube that change the account dimension very often. So the cube have an CalcScript that need to be updated every time the dimension changes.
For that purpose, we have a process that read the database and recreate the calc with the correct members.
I never tested that solution with calc manager, but i think it's less complex than recognize the member itself during calculation.
