If else condition at query designer.

Dear All,

I have a requirement to calculate Aging buckets based on two KF (e.g. K10 and J10) for current, > 30days and > 60days. 

As per requirement excel formula as below by bucket.

Please advice how can we calculate in query designer.

current                              | > 30 Days                                                       | >60days

=IF(K10<=30,J10,"")     | =IF(AND($K10>30,$K10<=60),$J10,"")     | =IF(AND($K10>60,$K10<=90),$J10,"")

Thanks in advance.

Regards

Naani.
