Hi @venkatch, 

It sounds like you just need to create a rule that uses a "contains" runtime function for the simple text box you want to hide/show.

Before you setup the rule, it is important the drop down list control has a value in the Name field in its Control Settings (otherwise the control will not be available as an option under "Named Controls" when setting up the rule formula).

Once the drop down list control is named, you can select the simple text box control and click Rules > Add Rule. Give the rule a name then click the f(x) button next to the When field to view the formula builder. Select the Runtime Functions tab then choose the "contains" function. The formula builder provides a template example once you select the function to assist with setup of the rule but I attached some screenshots in hopes that also helps. 

Basic sample example of the formula = 

!contains(DropDownListControl, DropDownListChoice)

You want to type an ! before the word contains in the formula builder because you want to hide the simple textbox if the drop down list does NOT contain a certain value. For the Then field on the rule you will choose the option "Hide."

Hope this helps! 

Hi Amy,

Wow, that worked fantastic.

Hi @venkatch apologies for the delay, I did not have my notifications setup so had not known you replied. I am very happy my suggestion worked well for you.

Since you have already marked this as solved I suggest you make another post for your other question. I am not completely sure I understand what you are asking to give any good suggestions but hopefully someone in the community can help.
