Working with an MVRS field that has the important fields of:
"drive_letter"
"capacity_in_gb"
What I am doing is working on an onChange Catalog Client script associated with the MVRS so that when they go to change the "capacity_in_gb" value for drive letters T and Y it compares that against the "capacity_in_gb" of Drive X and will give them an error using showFieldMsg if the new value for the T or Y drive they are changing is greater than X.
The problem I am running into is I cannot figure out how to get what the "drive_letter" value is of the entry they are presently changing in the popup. Here is screenshot, basically when they enter a new value in the capacity, I want it to grab the value in the drive letter box and if T or Y check the NewValue against the capacity of the X drive from the MRVS (which I have already gathered and put to a variable).
Thanks ahead of time for any assistance.
