Let me preface this that I am not a developer and I don't normally work in SSRS. 

I am receiving `Textbox16.Paragraphs[0].TextRuns[0]` contains an error: 

```
[BC30034] Bracketed identifier is missing closing ']'.

```

The expression in Textbox16 is 

```
=IIF(ReportItems!Pallets.Value=0,[Sum(NumUnits)]*ReportItems!FloorLocations.Value,[Sum(NumUnits)]*ReportItems!Pallets.Value)

```

I tried just `=[Sum(NumUnits)]*ReportItems!FloorLocations.Value` and get the same error. 

What am I missing?
