Because this came up just now with the collosseum favorite thingy :
Q: What does the "indirect" function do.
A: Let's look at the formula in the betting thingy : =IFERROR(INDIRECT(""&A3&"!G7"))
A3 is the number representing the player. So for example; jenkar's sheet being sheet 16, on that line it'd be interpreted as :
=IFERROR(INDIRECT("16"!G7")), which, with the use of indirect, does : =IFERROR(16!G7). Indirect converts a string in a reference.
Note on references : references are of the form : <sheetname>!($)<column>($)<row>. The <>'s are for indicating beggining/end of field, you don't type them in a ref. Also, the $ are optionnal (hence the parenthesis, again not typed () ), and they serve to indicate an absolute reference. There are two $ possible placement, one for absolute column and one for absolute row. (Using both gives absolute cell reference). What is an absolute reference? If you drag a cell, the formula will be copy pasted into the cells you drag along, AS IF YOU MOVED THE REFERENCE TOO. This is relative referencing. Absolute means the references stay the same.
