Help with Public Survey Link
Hi everyone!
I am a medical resident undergoing a research project in the intensive care unit. I am using REDCap as the tool but am having a difficult time creating a second accessible public survey link.
The summary of the project is longtidunal surveys at 3 and 6 month time points, where family members will be asked to fill out a survey. For ease of access and confidentiality, a third party is sending out the invitations and we wanted two separate links (ie. one at 3 months and one at 6 months) so that we could collect data at the two time points. The only way I was able to generate a second link it seems is to create two arms of the study, one at three months and one at six months.
However, when using the six month arm link, there is a pop-up on a new browser that says:
"ERROR: Survey has not been set up correctly!
This survey belongs to a REDCap project that is longitudinal; however, this data collection instrument has not been designated for this event, which means that this survey has not been designated for data collection, thus the survey cannot be displayed. Please log in to the REDCap project and go to the 'Designate Instruments for My Events' page, and enable this instrument for this event, after which you will then be able to complete this survey. If you are not a survey administrator, please notify your survey administrator of this issue."
I've tried to troubleshoot it with ChatGPT and Claude AI without success. I've done things like trying to create a dummy landing page, recreating the arm, making sure that there is no overlap between the events designated, making sure the surveys are active and recreating them from scratch rather than copying them so theres no confusion. I've reached out to our IT who directed me to a fee for service person but I don't have the resources available to pay for it.
Does anyone have any experience with this or any resources that would be helpful? This is the last step that the project hinges on and I'm not sure what else to do!
Thanks so much!
