I'm planning to wrap my FormFunction expression in Cloulddeploy but am having trouble giving input to the required data to Encde, the function I want to run inside FormFunction. Encde runs fine in a notebook on its own, but not inside FormFunction. The websites I've looked at for help (with my untrained eye, including Mathematic.SE) seem to offer contradictory examples of how the function is suppose to be formatted inside FormFunction.

What is the correct way to include a user defined function inside a FormFunction expression?

Encde[v1_, p1_] := 
 TableForm[
  Flatten[
   ToUpperCase[
    IntegerString[
     {Times[ToExpression[ToCharacterCode[v1]], p1]}, 16]] 
    ], TableDirections ->Row
   ]

FormFunction[{"v1"->"String", "p1"->"Integer"}, Encde]
