Hidden tables in spreadsheet

I am working on a spreadsheet created by a former colleague who had extensive knowledge of excel.
It is a database of courses (drop down list) costings (Calc from a table) and generation of final costing.
I have found where I think the table is based and can add another training course. This displays on the drop down list. However even though I add in a cost. As soon as I add the new course from the drop down list on the working page it displays an error message in the final calculation of total. Cell that should show the cost pp doesn't display the value.

Please can anyone help me.

RE: Hidden tables in spreadsheet

Hi Hilary,

Thank you for the forum question.

I don't believe it has something to do with the drop down list. It can be something to do with the formatting. Well there can be a lot of reason.

All numbers in the calculation must be formatted as numbers. It could also be if Lookup functions cannot find the new training course.

If you want I can have a look at your file.

Please send the file to:

Excel tip:

Sum Up All the Values in A Column

If you want to quickly calculate the Summed values of all cells in a column in Excel 2003 normally you would use the SUM formula. (eg if you wanted to calculate the values in Column C rows 10 to 25) the formula would be:

=SUM(C10:C25)

However, if you keep adding values to column C you would keep having to modify the above SUM formula which can get quite annoying.

To get around this you can sum all the values in a column using the following formula:

=SUM(COLUMN:COLUMN)

Which, in our example, would be:

=SUM(C:C)

NOTE You cannot place this formula in column C, or else Excel 2003 will show a circular reference error.

The formula must be placed in any other column, EXCEPT the one being calculated.
