add to array formula to only return unique values

All,

I have the following array formula and would like to add something so it only returns a unique value (no duplicates). I can create this array then use a COUNTIF array to relist, however the reference value i'm using to determine the number of cells to perform this action with only counts unique values so the resultant "reference" value is lower than the number of cells this forumla would need to run in to capture all values.

Array:
=IFERROR(IF(ROWS(C$20:C20)<='INFO Sheet'!E$9,INDEX('UNI Delivery Report 6-6'!B2:P10000,SMALL(IF('UNI Delivery Report 6-6'!B2:B10000=C$15,ROW('UNI Delivery Report 6-6'!B2:B10000)-ROW('UNI Delivery Report 6-6'!B2)+1,""),ROWS(C$20:C20)),15),""),"")

Problem:
INFO Sheet e9=2
Column 15 has my returned value, but contains duplicates and only the first 2 occurences that meet the critera are returned eliminating additional entries. The "INFO Sheet E9" cell counts the number of unique values so I need the list to also only contain unique values.

Any ideas??? Thanks in advance.

Care to post the formula you apparently have in E9 on INFO Sheet?

Yes.

Cell E9 is the second of a 3 part "process". The first formula is a simple vlookup that returns a value:

This is in cells E30:E41:
=IFERROR(VLOOKUP(VALUE(D30),'UNI Delivery Report 6-6'!A:L,10,0),"")

From there, cells C9:C13 have each unique value returned and quantify the number of occurrences the values returned in E30 to E41:

Cell E9 (arrayed to E13):
=IF(C9<>"",SUM(IF(FREQUENCY(IF('INFO Sheet'!$E$30:$E$41=C9,MATCH('INFO Sheet'!$B$30:$B$41,'INFO Sheet'!$B$30:$B$41,0)),ROW('INFO Sheet'!$B$30:$B$41)-ROW('INFO Sheet'!B$30)+1),1),IF('INFO Sheet'!$C$68=B9,1,0)),"")

Would you upload the file if possible?

The book is 93 meg, so uploading isn't a good option....

I think I have found a workaround by sorting the indexed sheet using a column with unique values that ascend, the array then only returns the first (x) occurrences which are also unique since the duplicates have been moved down. I believe this will work since all of the entries have 2 duplicates with each one tied to a "value-1" and the second duplicate tied to a "value-2".
