Indirect Functions And Date Ranges?

I have an INDIRECT function set up which should, in theory, concatenate data from a date range listed in another cell to correctly reference an external spreadsheet, which is named based on the date range it is generated for. The issue I'm running into is that the program which generates the external spreadsheet uses an MMDDYYYY format when naming its output file. This works fine if the month and day are both 10 or greater, but if they are less than 10, it doesn't work - for example, my INDIRECT function would return the date 5/3/13 as 532013, whereas the file name would be 05032013. I was contemplating using a series of IF statements to fix this, but there has to be a simpler way. Here are the relevant functions.

Function which generates date range (later used in INDIRECT function):

=MONTH(MIN(TransData!A2:A9882))&"/"&DAY(MIN(TransData!A2:A9882))&"/"&YEAR(MIN(TransData!A2:A9882))&" - "&MONTH(MAX(TransData!A2:A9882))&"/"&DAY(MAX(TransData!A2:A9882))&"/"&YEAR(MAX(TransData!A2:A9882))

TransData is a different sheet within the same workbook where the various dates are stored in column A. I found that I needed to format the formula like this in order to get it to return actual dates instead of date sequence numbers.

=AVERAGE(INDIRECT("'[DCQA_"&SUBSTITUTE(B4,"/","")&".xlsm]Total'!$C$3:$C$46"))

Cell B4 is where the date range formula listed above lives. "DCQA_" is the beginning of the filename of the external sheet, followed by the date range in MMDDYYYY - MMDDYYYY format. So, the sheet for 12/2/13 to 12/7/13 would be named DCQA_12022013 - 12072013. I'm unfortunately unable to change the way the external program names its output sheets, so I have to fix this from within my workbook.
