1) The attachment (Output.bmp) is the final output after mycoding (Codes.txt). So right now I would need to filter some codesout. 2) Look at the textfield from Node selection expression:This would be the filter. Right now it is all. It basically meansall nodes will be exported. However this is not what I want. WhatI want is only export nodes with ui3. ui3 is nothing but a ID andit represents major intersections. 3) Right now once I typedsomething in the Node selection expression: textfield the systembasically return an error. (Error.bmp). After consulting my leaderit was made known to be that we would be mostly dealing with ui3.4) Instead of a textfield you could maybe create a drop down listwith 2 options (ui3 All). In this case if an user selects theoption of ui3 he/she will only get back those nodes with ui3.Similarity if a user were to select All the solution would justbe like the current code.
