Use Upper Function in Text

[CemileDemirci]

Is it possible to use the UPPER function for only the first letter from a Data Item ? How can i do this? I use this but all the same letter wil be Uppercase Replace([Data1]; Left([Data1]; 1); Upper(Left([Data1]; 1)))   if the word is test it will be formatted to TesT

Upper(Left([Data1], 1))&Lower(Mid([Data1], 2, Len([Data1])))
