    automatically re-number records in a query

    I am using an Access table to create a "Table of Contents" for AutoCad drawings.

    Database Properties Error Message

    Summing Values from a table

    SELECT [RM#], (SUM([L/S(max)]) + SUM([L/S(min)])) As TotalSum FROM TerminalUnits GROUP BY [RM#] sums the min and max, I need to sum 2 max's together and 2 min's together. (See my above example and how I added them together for rooms 1.16 and 1.20)

    Summing Values from a table

    I'm sorry for the confusion, I wrote a wrong piece of information in my question, the sums should equal eachother, meaning the difference would be zero. Here are sample values in the table named Terminal Units: Rm# L/S(max) L/S(min) 1.16 -445 -240 1.16 350...

    I have a table that gives detailed information about what is located in certain rooms of a large building. It includes columns of positive and negative values for each entry. For each room number, the values, when summed, should equal zero. How can I create a query to sum the values in each...

    converting units in Access

    I have a table with various flowrates in liters/second. I would like for them to be in gallons/minute. I know the conversion factor is 1 L/S= 15.82 GPM. How can I use Access to convert all of the values in the column from L/S to GPM?

    counting entries

    I have a query that contains a list of part number's. There are 4 different part numbers that repeat. How can I make a table or query that totals how many I have of each part number? (Should I be using DCount?)
