Flow does not run. I think it is rejecting a string because it contains a number.

I am having trouble getting this flow to run:

ClearCollect(
    colDbResults,
    IPL_GI_AddBlobStorageRecord.Run(
        locID,
        gblSentBlob.Id,
        locComment,
        gblSentBlob.DisplayName
    )
);
If(
    CountRows(colDbResults) < 1,
    Notify(
        "No response from Flow.",
        NotificationType.Error
    ),

In my flow I have initialized the variable:

It has to be a string variable because most of these stock codes are strings. However, some of them are numbers. In this case 66.

There is no run history, and my collection colDbResults is returned empty.

How can I get this to work?

I seem to have solved it using this Expression in my Variable Initializer: 

string(triggerBody()['varStCode_Value'])
