Thanks for any and all replies in advance!
I am trying to create python script tool that uses the merge tool but I am having issues getting the field map to show and populate as I add features. As of now, it won't even populate. However, if I recreate this using ModelBuilder, it works as intended. I am starting to think I need to get into Tool Validation.
Here is the part I am having issues with:
<SPAN class="keyword token">import</SPAN> arcpy
<SPAN class="comment token">#input features. Set output for merge</SPAN>
polygonsToUse <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>GetParameterAsText<SPAN class="punctuation token">(</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">)</SPAN>
mergedPolygons <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>GetParameterAsText<SPAN class="punctuation token">(</SPAN><SPAN class="number token">1</SPAN><SPAN class="punctuation token">)</SPAN>
<SPAN class="comment token">#get field map so user can remove unneccessary fields</SPAN>
fieldMap <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>GetParameterAsText<SPAN class="punctuation token">(</SPAN><SPAN class="number token">2</SPAN><SPAN class="punctuation token">)</SPAN>
<SPAN class="comment token">#merge polygons</SPAN>
arcpy<SPAN class="punctuation token">.</SPAN>Merge<SPAN class="punctuation token">(</SPAN>polygonsToUse<SPAN class="punctuation token">,</SPAN>mergedPolygons<SPAN class="punctuation token">,</SPAN>fieldMap<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN></SPAN>
and here is a screenshot of my script tool parameter setup:

Thank you!
