This works exactly as advertised:

1st step: minivend tag Interpolation
2nd step: Execution of perl code

This means that ALL your minivend tags in your perl code are interpolated,
before any perl will be executed, thus the code fails during the
interpolation step.

You could do:
[data base="albums" field="small" key="[perl interpolate=1]
$sku="12345";
$sku;
[/perl]"]

or:
[perl]
$sku="12345";
"\[data albums small $sku\]";
[/perl]

Cheers, Frank
