Hi, I have VB script query for BarTender 10.1 SR4

I'm trying to replace text "700mA" with "500mA" within a text object populated from a database field "Languages$.Main Text A", but conditionally based on a Check Box Control "Variable" with value either "01" or "02".

I'm thinking something like the following (which doesn't work):

IF Format.NamedSubStrings("Variant").Value = "01" THEN
    Field("Languages$.Main Text A").Value = Replace(Field("Languages$.Main Text A"), "700mA", "500mA")
End If

I'd be grateful if someone could give me some guidance on getting this to work.

Thanks, Justin
