bash script function while loop

Please look at this code; working on walking through directories that are in the current folder? Currently getting “line 15: ${1}: ambiguous redirect” any ideas? #!/bin/bash echo "starting" while read folder || [[ $folder ]]; do echo "folder: $folder" changeConfig $folder done < ${1} changeConfig () { echo "one 1 value: $1" cd $1 echo "$PWD" } General Details Please only BID if you know how to do this and are certain you can do this? Expecting this is something easy for about $10 or so and will be something person on this topic would know and understand. Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Can you work on this and finish now? Need this basically in 2 hours, possible? Will need to work on Desktop Sharing? After done; can we test on Hangouts? After done; can we test on Skype? After done; can we test on Team viewer? After done; can we test on Anydesk? Is $10 ok? (If not how much?) (Please note I am out of work and have a small budget) (Did I miss something?) (Sorry I am broke, but that is about my budget) Is this something you can work on now? If not now, please share how soon? We can work on Google Hangouts/Skype/Team viewer/Anydesk or any desktop sharing you may have? Please share your thoughts? If you have questions please confirm you read all of this, before reaching to me. My first question to you will be; did you read the project details? Please only BID if you know how to do this and are certain you can do this? Expecting this is something easy for about $10 or so and will be something person on this topic would know and understand. Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Please keep this a positive experience; and agree to do both our parts to ensure that. Please note I need this in 2 hours, if you cannot do that, please speak to me, don’t bid or cancel your acceptance of the project. Please just don’t ask me to give you the root password; that will tell me you have not read even anything on these requirements. There is hope you will read this all and ask a question; rather than tell me more about this, as I have exhausted every detail I know right now, and hope you will ask something that will lead this down a positive direction.
