The skill section is a repeating section? and you want to use the modifier from a specific row in the other repeating section? The picture you have doesnt look like a repeating section. And honestly, if you want to proceed with this, you are better off making your skill section a fixed list, not a repeating section. You can use CSS to hide those that players dont have. But if you have a defined skill list, you should set it up as a fixed set of attributes, not a repeating section. That makes the coding easier, and also makes it easier for players who want to make their own macros to use the skills in their macros. If you insist on keeping them both as repeating sections, it gets very complicated, for more than one reason: First, you need some way of matching up which row contains the weapon skill. If you dont define it, your sheet worker has to watch the entire repeating section, and every time every attribute changes, it has to check if the skill that changed is the one relevant to the other section, then it has scan the entire weapon repeating section and change the attribute on every row of that section. So you will need the getSectionIDs function, and worse, will need to nest two instances of it, once for each repeating section. Your going to have loops within loops. There's another issue: How is the name Handheld being entered into a box? Is it in a select? If it's in an input, this is pretty much a non-starter, because as you've found, names in sheet workers have to be spelled exactly, and players will make typos. Some typos will simply fail, others might crash the sheet worker if not properly handled. Also what happens if they enter handheld on two rows of the repeating skill section? My recommendation: if you have a defined skill list, don't make that a repeating section. You can create the code for all the skills, then use CSS to hide the ones players arent skilled in. You'll still have to use getSectionIDs for the repeating_rangedweapons section, but the code is massively simpler and safer with a defined skill attribute name to use.
