Passing paramaters / variables thru Select Layer By Location

Good afternoon all

Having some issues with the Select By Location function returning an odd error message that I can't shake out.

I'm pretty confident it's falling over on the first half of the if..else command. This is in there to differentiate between features which need to be checked with a buffer distance and those that don't (this bit of code will be iterated through all the features in a dataset individually).

Code (or snippets of):

sqlquery = OIDFieldName + "=" + str(oid)
dataset_tocheck_lyr = arcpy.MakeFeatureLayer_management(dataset_tocheck, "dataset_tocheck_lyr", "\"sqlquery\"")
themelocation_lyr = arcpy.MakeFeatureLayer_management(themelocation, "themelocation_lyr") #create temp layer of theme location
bufferdist = str(int(overlayfeature.DIST)) + " Meters"
.
.
.
                    
                if int(overlayfeature.DIST) == 0: 
                    arcpy.SelectLayerByLocation_management(themelocation_lyr, "INTERSECT", dataset_tocheck_lyr, "","NEW_SELECTION")
                    output_text.write("Buffer is zero, not factoring into SBL\n\n")
                else:
                    arcpy.SelectLayerByLocation_management(themelocation_lyr, "INTERSECT", dataset_tocheck_lyr, "\"bufferdist\"", "NEW_SELECTION")
                    output_text.write("Buffer is not zero, factoring additional string into SBL\n\n")


Error:

Traceback (most recent call last):

This has thrown a few other problems at me, which I have so far been able to solve, but this one has got me stuffed.

Any thoughts?
