Pushing Items onto Array

Your all cribs array object should be created with square brackets, using braces creates an object not an array object. I'm going to take a guess here and assume you were trying to append the value with a string "CribNumber" before adding it to array.

function readAllCribs() {


    var allCribs = [];
    
    Project.Variables.Cribs.Reset();
    while (!Project.Variables.Cribs.IsEOF() {
        allCribs.push("CribNumber" + Project.Variables.Cribs.Value); 
        Project.Variables.Cribs.Next();
    }




}

}
