There is an issue with suspended Forms that I have come across and that is mentioned many times in Answers.
If a Forms process gets suspended due a missing email address or an incorrect or missing variable, there is no way to get it moving again.
For example if I use a lookup to fill a variable for an email notification address and the lookup fails or there is no variable available. The Forms process will get suspended with no way of fixing the variable. You could go into the process editor and temporarily add an email address, but this would affect all other instances.
How about, when a forms process is in a suspended state, an administrator could go into Forms Monitor, find the offending variable and fix it.
We can already list the variables. All we need is the ability to edit them and select Re-try.
In this way you could add a variable value or an email address etc. and get the process moving again instead of having it sit there forever or having to restart what could be a very complex process involving numerous users.
