I have a datapage that utilizes virtual fields to collect user input values that I don't want to store in tables, but do want to use for some generally simple calculations. However, because virtual fields don't store the input as numeric, I keep getting calculation errors. Here is a simple example of one calculation that I can't get to work:

VirtualField1 is a text box

VirtualField2 is a dropdown with the options "in" and "mm"

VirtualField3 is a calculated field with the following formula:

CASE

WHEN [@cbParamVirtual2] = 'mm' THEN [@cbParamVirtual1]/25.4

ELSE [@cbParamVirtual1]

END

No matter what tweaks I have tried, I either get a "calculation error" message or just nothing appears in the VirtualField3. Any suggestions would be greatly appreciated. Thanks!
