( if not isnull({#RInvAmount}) and not isnull({#RPaymentAmount}) and {#RInvAmount} >0 then 
     (amount121 := amount121 + ({#RInvAmount}-{#RPaymentAmount}); 
     {#RInvAmount}-{#RPaymentAmount};) 
    else if not isnull({#RInvAmount})and {#RInvAmount} >0 then

Tamam mümkün olduğu ölçüde açıklamaya çalışacağım formülde bağlanmış olan bir başka formüller: sonra metin kontrol //

shared numbervar amount121 ; //Varible decleration with shared scope 

if {hdr.postdate} <= DateAdd("d", - (181+{@PatermDays}), {@postto})  //"d" deleting those many number of days and coverting resultant to datetime 

and ({dtl.cleardate} = cdate('01/01/1900') or {dtl.cleardate} > {@postto})then  //Cdate converting string to date used for comparing the date field 

( if not isnull({#RInvAmount}) and not isnull({#RPaymentAmount}) and {#RInvAmount} >0 then  //Comparing the running totals that are not null 

     (amount121 := amount121 + ({#RInvAmount}-{#RPaymentAmount});  //subtracting and storing values in variable 

     {#RInvAmount}-{#RPaymentAmount};)  //Not sure what is this doing here 

    else if not isnull({#RInvAmount})and {#RInvAmount} >0 then  //If fails then using other running totals in else if 

     (amount121 := amount121 + {#RInvAmount};  //Again storing values in else if 

     {#RInvAmount};)  //Not sure what is this doing here 

    else  //if and else if fails then control comes to this part
