What am I doing wrong?

This is the error I'm getting:        TypeError: Cannot read property 'substring' of undefined &{template:default} {{name= @{selected|token_name}'s SKILL CHECK}} {{Roll: = Effect [[2d6 +?{Task difficulty?|MODERATE (+0), 0 [Moderate task]|Simple (+6), 6 [Simple task]|Easy (+4), 4 [Easy task]|Routine (+2), 2 [Routine task] |Difficult (-2), -2 [Difficult task] |Very Difficult (-4), -4 [V Difficult task]|Formidable (-6), -6 [Formidable task]} +?{Ability|STRENGTH, @{Strength} [STR]|DEXTERITY, @{Dexterity} [DEX]|ENDURANCE, @{Endurance} [END]|INTELLIGENCE, @{Intelligence} [INT]|EDUCATION, @{Education} [EDU]|SOCIAL, @{Social} [SOC]|} +?{Skill Level?|NO SKILL, -3 [No skill] |0,0 [skill]|1,1[skill]|2,2 [skill]|3,3 [skill]|4,4 [skill]|5,5 [skill]|6,6 [skill]|} ?{Other Modifiers|0}[DMs] -8 [to find effect] ]]}}

You may have to make some html substitutions for special characters in your queries. ie substitute " } " for any closing curly bracket used outside of an attribute call.  More info on the wiki:  Advanced Usage for Roll Queries . I would also suggest adding padding (space) before and after any double square brackets used for inline rolls.

See if this works Updated: Silvyre's helpful insight. (added "selected|" to the attribute calls) &{template:default} {{name= @{selected|token_name}'s SKILL CHECK}} {{Roll: = Effect [[ 2d6 +?{Task difficulty?|MODERATE (+0), 0 [Moderate task]|Simple (+6), 6 [Simple task]|Easy (+4), 4 [Easy task]|Routine (+2), 2 [Routine task] |Difficult (-2), -2 [Difficult task] |Very Difficult (-4), -4 [V Difficult task]|Formidable (-6), -6 [Formidable task]} +?{Ability|STRENGTH, @{selected|Strength} [STR]|DEXTERITY, @{selected|Dexterity} [DEX]|ENDURANCE, @{selected|Endurance} [END]|INTELLIGENCE, @{selected|Intelligence} [INT]|EDUCATION, @{selected|Education} [EDU]|SOCIAL, @{selected|Social} [SOC]|} +?{Skill Level?|NO SKILL, -3 [No skill] |0,0 [skill]|1,1[skill]|2,2 [skill]|3,3 [skill]|4,4 [skill]|5,5 [skill]|6,6 [skill]|} ?{Other Modifiers|0}[DMs] -8 [to find effect] ]]}}

KenB said: TypeError: Cannot read property 'substring' of undefined @{Strength} From the Wiki: Attribute calls (e.g. @{AC}) that are not placed within one of tabs of a Character Window (e.g. within a field on the Character Sheet Tab or within an Ability on the Attributes & Abilities Tab ) must use a keyword to let the parser know which Character you intend to call that Attribute from (e.g. @{selected|AC}).
