Looping through txtboxes, cboboxes and taking values

Hi,

I have a form which needs to cycle through all the controls on a form and pulls the data from each and pastes them into a multiline text box when a user clicks the command button.

The data pasted must only be the data selected, that is to say that the controls that are disabled or not chosen must not have their data pulled. All the boxes contain default text such as "Please Select"

Based on the criteria selected some of the controls become enabled/disabled.

I had it working to a point with some simple if /elseif logic but used in conjunction with a variety of AND and OR it started not pulling the data (I was simply outputting the text to a textbox)

Ideally I need it to cycle through all the controls, establish if the default text is there, if it is ignore it, if not take it and pass it to something to store (an array maybe)

any help would be greatly appreciated, thanks
