Hello,

We are attempting to incorporate the "Bladder Cancer Diagnosis" using a .relatedTo attribute into the "First Bladder Cancer Staging Procedure" definition in CMS646 since the logic as it currently exists looks at any tumor staging. We have been making adjustments to the logic but cannot seem to get it to function as expected without any errors. I have attached the export of the CQL with the version that generates the least amount of errors. It is our belief that there is likely something small that we have missed in constructing this definition. 

We have been referencing the following logic sequence from CMS129 as a model.

define "Most Recent Prostate Cancer Staging T1a to T2a":

( Last((["Procedure, Performed": "Tumor staging (tumor staging)"] ProstateCaStaging
    where exists("Prostate Cancer Diagnosis" ProstateCaDx
        where ProstateCaDx.id in ProstateCaStaging.relatedTo)) ProstateCancerStaging
    with "First Prostate Cancer Treatment during day of Measurement Period" FirstProstateCancerTreatment
        such that Global."NormalizeInterval"(ProstateCancerStaging.relevantDatetime, ProstateCancerStaging.relevantPeriod) starts before start of Global."NormalizeInterval"(FirstProstateCancerTreatment.relevantDatetime, FirstProstateCancerTreatment.relevantPeriod)
        sort by start of Global."NormalizeInterval"(relevantDatetime, relevantPeriod)
    ) ) LastProstateCancerStaging
    where ( LastProstateCancerStaging.result ~ "American Joint Committee on Cancer cT1a (qualifier value)"
        or LastProstateCancerStaging.result ~ "American Joint Committee on Cancer cT1b (qualifier value)"
        or LastProstateCancerStaging.result ~ "American Joint Committee on Cancer cT1c (qualifier value)"
        or LastProstateCancerStaging.result ~ "American Joint Committee on Cancer cT2a (qualifier value)"
)
 
Thank you in advance for your help on this matter.
