String & Numeric Expressions

String Expressions

Concatenating strings: When you want to make a string value a combination of fixed text and or other string values, use concatenation within the expression:

[StringField1] + '-' + [StringField2] + '-' + [StringField3] + '-' + YEAR([DateField1])

String([NumberField1])

Returns a number value as a string.

Substring([TextField1], StartFrom, NumberOfChars)

Returns part of a string field, where the first parameter is the field being looked at, the second is the starting position, and the the third parameter is the number of characters needed to return
NOTE: if the string is not long enough, an error is returned, so you may need to use Len() first e.g. If(Len([FieldName]) > 50, Substring([FieldName], 0, 50), [FieldName])

Len([TextField])

Returns a numeric value representing the number of characters in a text field

stringReplace([TextField], 'valueToReplace','valueToReplaceWith)

Takes a string value from a Field and replaces where the text in paramater two appears with the text in parameter three. If the value in [Title] is 'Mark to assess Risk'

stringReplace([Title], 'Mark', 'John') would give 'John to assess Risk'
