Receiving error 'The function expression is invalid' for InsertData ampscript function

Question

I'm using a Marketing Cloud Cloud Page to sync contact/lead records from a Data Extension to corresponding Sales Cloud Campaigns (as campaign members). This part is working well. However I'm receiving an error when I try to write information into a Data Extension by using the InsertData function. I'm getting the following error when I add the InsertData function into my code.

Here is my code for InsertData:

InsertData('SubscriptionSyncLog',
'SyncTime', @localTime, 
'UniqueId', @uniqueId,
'LookupValue', @rowValue, 
'SubscriptionId', @subscriptionId, 
'CampaignId', @campaignId, 
'Message', @outcome
)

Here is the entire cloud page code:
