	Hello Yes that's correct, the SFE_CFEE is a string which i'm guessing is where it's failing. Thanks

	convert the text to a numeric field //number_FEE val({SRS_SFE.SFE_CFEE}) I assume this value is the same for all rows in the group you can then insert a summary on this formula field at the group level maximum({@number_FEE},{group}) now in the select criteria you change it to the group select criteria and use the summary conditions here to excldue the whole group frmt he report maximum({@number_FEE},{group field})=sum({other_formula},{group field})

	Hello Sorry i'm back again! This doesn't seem to be working quite as i would expect it to, I have listed an example below, is anybody able to help me identify where it is going wrong? customer has one credit type{SRS_FDU.FDU_CORD} record of 1,000.00 summing correctly with this forumla :if {SRS_FDU.FDU_CORD}='C' then {SRS_FDU.FDU_AMNT} customer has one debit type{SRS_FDU.FDU_CORD} record of 9,000.00 summing correctly with this formula: if {SRS_FDU.FDU_CORD}='D' then {SRS_FDU.FDU_AMNT} this formula does not seem to be displaying as i would expect: if {SRS_FDU.FDU_CORD}='C' then {SRS_FDU.FDU_AMNT} else {SRS_FDU.FDU_AMNT} *(-1) - i would expect to see -8,000.00 but is showing me -9,000.00 if i do a sum of this sum then the correct amount is displayed but i am unable to use this to compare with SFE_CFEE as above. any advice? thanks

	it is showing exactly what it is expected to show. All the fomrula is doing is leaving credits as a positive value and making debits a negative value. So when you go to sum this formula field it will give you the total of all credits - the total of all debits. if you need to see it change row by row use a Running Total. right click on Running Total select new name='Total" (or whatever) field to summarize= the formula field above (if {SRS_FDU.FDU_CORD}='C' then {SRS_FDU.FDU_AMNT} else {SRS_FDU.FDU_AMNT} (-1)* ) summary type=sum evaluate= for each record reset=never if you want it to keep showing changes for every row or on change of a group if you want to start fresh on a new grouping place it in the detail row to see row by row changes place it in a footer to see the total only Edited by DBlank - 06 Nov 2012 at 5:15am

	Thanks for the prompt reply, makes sense to me now. My running total is now displaying the figure as a - but the field i need to compare it to doesn't do this, is there a way to strip this off for the comparison? Thanks

	is it it corerctly showing as a negative value (meaning there were more debits than credits? If so just add teh 2 values together. If they = 0 then they are 'the same number' (one positive and one negative) maximum({@number_FEE},{group field}) + sum({other_formula},{group field}) = 0
