I recently built a rogue4/wizard4 character that somehow wound up with level 3 spell slots and that isn't right unless I'm missing something. Is there an interaction going on I'm not aware of or is Beyond just not getting it right?

Are you an Arcane trickster rouge?

Also, please post a link to the character sheet.

If your Rogue subclass is Arcane Trickster then that is the correct spell progression. As per the rules for multiclass spellcasters: 

Spell Slots. You determine your available spell slots by adding together all your levels in the bard, cleric, druid, sorcerer, and wizard classes, half your levels (rounded down) in the paladin and ranger classes, and a third of your fighter or rogue levels (rounded down) if you have the Eldritch Knight or the Arcane Trickster feature. Use this total to determine your spell slots by consulting the Multiclass Spellcaster table.

If you have more than one spellcasting class, this table might give you spell slots of a level that is higher than the spells you know or can prepare. You can use those slots, but only to cast your lower-level spells. If a lower-level spell that you cast, like burning hands, has an enhanced effect when cast using a higher-level slot, you can use the enhanced effect, even though you don’t have any spells of that higher level.

This is what I was missing, thank you!
