Re: Where is my foreach data going to?

Looking at your code ...

@athlete[$i,$j++] = $bug ;
[download]

Is actually an array slice. You probably wanted this instead:

$athlete[$i,$j++] = $bug;
[download]

It's pretty easy to mistake array slices for array indices.

Did you try running `$athlete[$i,$j++] = $bug;` [download] with warnings on? It doesn't mean at all what you thing it means. `$ perl -wcle '$i = $j = 0; $athlete [$i, $j ++] = 1' Multidimensional syntax $athlete [$i, $j ++] not supported at -e l +ine 1. Useless use of a variable in void context at -e line 1. Name "main::athlete" used only once: possible typo at -e line 1. -e syntax OK` [download] If you want to use multi-dimensional arrays, you have to use the correct syntax: `$athlete [$i] [$j ++] = $bug;` [download] Abigail	[reply] [d/l] [select]

Your change yielded these results: @athlete[$i,$j] is assigned the value 0.4 Small Bunch Grapes $bug is assigned the value 32 $i$j is assigned 4:2 @athlete[$i,$j] is assigned the value 0.4 carb $bug is assigned the value Medium Pear $i$j is assigned 4:3 @athlete[$i,$j] is assigned the value 0.4 15 $bug is assigned the value carb $i$j is assigned 4:4 @athlete[$i,$j] is assigned the value 0.4 0.4 $bug is assigned the value 16 $i$j is assigned 4:5 @athlete[$i,$j] is assigned the value 0.5 0.1 $bug is assigned the value 0.5 $i$j is assigned 4:6 @athlete[$i,$j] is assigned the value 0.5 $bug is assigned the value 0.2 [download] To be honest, I'm more confused now than I was when I first made this post.

You need to replace all `@athlete[$i,$j]` with `$athlete[$i,$j]`, even with your print statement. Because the syntax `@athelete[$i,$j]` is wrong. ;-) To understand why, you need to understand what is an array slice ...	[reply] [d/l] [select]
